Assume ideal behavior. How many moles of are needed to fill a 2000L weather balloon at 210K and 1atm pressure? Round your answer to the nearest mole (use R = 0.082057 L atm mol-1K-1)

Answers

Answer 1

Considering the ideal gas law, 116.06 moles of are needed to fill a 2000 L weather balloon at 210 K and 1 atm pressure.

An ideal gas is a theoretical gas that is considered to be composed of randomly moving point particles that do not interact with each other. Gases in general are ideal when they are at high temperatures and low pressures.

The pressure, P, the temperature, T, and the volume, V, of an ideal gas, are related by a simple formula called the ideal gas law:  

P×V = n×R×T

where P is the gas pressure, V is the volume that occupies, T is its temperature, R is the ideal gas constant, and n is the number of moles of the gas. The universal constant of ideal gases R has the same value for all gaseous substances.

In this case, you know:

P= 1 atmV=2000 Ln= ?R= 0.082057 [tex]\frac{atmL}{molK}[/tex]T= 210 K

Replacing in the ideal gas law:

1 atm× 2000 L = n× 0.082057 [tex]\frac{atmL}{molK}[/tex]× 210 K

Solving:

[tex]n=\frac{1 atmx 2000 L}{0.082057 \frac{atmL}{molK}x 210 K}[/tex]

n=116.06 moles

Finally, 116.06 moles of are needed to fill a 2000 L weather balloon at 210 K and 1 atm pressure.

You want to replace the resistor in your
boiler with a more efficient one during win-
tertime. Would you replace it with another
one double the length or half the length?

Answers

To make the boiler more efficient, we would replace the resistor with another double the length.

We know that the resistance of the resistor in the boiler is given by R = ρl/A where

ρ = resistivity, l = length of resistor and,A = cross-sectional area of resistor.

Also, the power generated by the resistor is P = i²R where

i = current and R = resistance.

If i is constant, we see that P ∝ R.

So, to increase the efficiency, the value of the resistance has to increase.

Also, since R = ρl/A and ρ and A are constant, we see that R ∝ l.

Since P ∝ R and R ∝ l P ∝ l.

So, to increase the efficiency, we would double the length of the resistor.

So, to make the boiler more efficient, we would replace the resistor with another double the length.

a 280 nm thin film with index of refraction 1.6 floats on waterwhat is the largest wavelength of reflected light for which constructive interference occur? answer in units of m.

Answers

Answer:

Inside the film the wavelength will be λ/n

For constructive interference to occur the film must be λf/4 thick where λf is the wavelength of the light in the film - there will be a 180 degree phase shift at the water/film interface since the index of refraction of the film is greater than that of water - and the light has to travel λ/2 inside the film for constructive interference to occur

280 nm / 1.6 * 4 = 700 nm is the greatest wavelength allowed

Note that 700 nm is also the upper wavelength of the visible spectrum

I need help to build a mouse trap race car for my science class and this is my final and these are the materials I have.

Answers

So, your science teacher has given your class the classic "mousetrap car" assignment: to make, design, and build a small vehicle powered by the snapping action of a mousetrap to make your car travel as far as possible. If you want to come out ahead of all the other students in your class, you'll need to make your car as efficient as possible so you can squeeze every last inch out of your "car". With the right approach, it's possible to streamline your car's design for maximum distance using only common home materials. You could also buy a mousetrap car kit from any craft store and skip wondering if it will work.

Use large rear wheels. Large wheels have greater rotational inertia than small wheels. In practice, this means that once they start rolling, they're harder to stop rolling. This makes large wheels perfect for distance-based contests — theoretically, they'll accelerate less quickly than smaller wheels, but they'll roll much longer and they'll travel a greater distance overall. So, for maximum distance, make the wheels on the drive axle (the one the mousetrap is tied to, which is usually the rear one) very large. The front wheel is a little less important — it can be large or small. For a classic drag racer look, you'll want big wheels in the back and smaller ones in front.

Use thin, light wheels. Thinner wheels have less friction and may go farther if the distance is what you want or need with your mousetrap racer. It's also important to take the weight of the wheels themselves into account — any unneeded weight will ultimately slow your car down or lead to added friction. In addition, it's worth noting that wide wheels can even have a small negative effect on the car's drag due to air resistance. For these reasons, you'll want to use the thinnest, lightest wheels available for your car.

Old CDs or DVDs work fairly well for this purpose — they're large, thin, and extremely light. In this case, a plumbing washer may be used to reduce the hole size in the middle of the CD (to fit the axle better).

If you have access to old vinyl, these also work extremely well, though they may be too heavy for the smallest mousetraps.

Use a narrow rear axle. Assuming your car is a rear-wheel-drive car, each time your rear axle turns, the rear wheels turn. If your rear axle is extremely skinny, your mousetrap car will be able to turn it more times for the same length of string than it would if it were wider. This translates to turning your rear wheels more times, meaning greater distance! For this reason, it's a wise idea to make your axle out of the skinniest material available that can still support the weight of the frame and wheels.

Narrow wooden dowel rods are a great, easily-accessible choice here. If you have access to thin metal rods, these are even better — when lubricated, they usually have less friction.

Create traction by giving the edges of the friction of the wheels. If the wheels slip against the ground when the trap is sprung, energy is wasted — the mousetrap works to make the wheels turn, but you don't get any extra distance. If this happens with your car, adding a friction-inducing material to the rear wheels may reduce their slippage. To keep your weight requirements down, use only as much as is necessary to give the tips of the wheels some grip and no extra. Some suitable materials are:[1]

Electrical tape

Rubber bands

Additionally, placing a piece of sandpaper under the rear wheels at the start line can reduce slippage as the car begins to move (when it is most likely)

The volume of water in the larger balloon is 8 times greater than in the smaller balloon

We'll begin by calculating the volume of each balloon.

For smaller balloon:Radius (r) = 3 cmPi (π) = 3.14Volume (V) =?

V = 4/3 πr³

V = 4/3 × 3.14 × 3³

V = 113.04 cm³

For larger balloon:Radius (r) = 6 cmPi (π) = 3.14Volume (V) =?

V = 4/3 πr³

V = 4/3 × 3.14 × 6³

V = 904.32 cm³

Finally, we shall determine how much greater the larger balloon is to the smaller balloon

Volume of smaller balloon = 113.04 cm³Volume of larger balloon = 904.32 cm³Greatness =?

Greatness => large / small

Large / small = 904.32 / 113.04

Large / small = 8

Cross multiply

Large = 8 × small

Therefore, the larger balloon is 8 times greater than the smaller balloon.

Who doesn't love a nice, cold scoop of ice cream on a warm day? For thousands of years, ice cream has been a decadent dessert loved by most people around the world.(2) There is some argument about who first invented ice cream. Some believe that ice cream was invented by the Chinese people anywhere from 2,000 to 6,000 years ago. They created a recipe of frozen milk and rice that was served as a dessert. Persia has also been credited with first serving frozen desserts. Over 2,000 years ago, the wealthy people of Persia enjoyed shaved ice from the mountains, covered with grape juice. They later learned to freeze rosewater and add different fruit toppings. These desserts were considered delicacies that only the richest families could experience. About 1,000 years after this, there is evidence that suggested Nero, the Roman Emperor, also enjoyed frozen treats and demanded that a constant supply of ice from the mountains be available to him. He liked to add honey to the top of his dessert.(3) Ice cream as we know it can be traced back to the 9th century in Arab cities, such as Baghdad, Damascus, and Cairo. Near the end of the 13th century, Marco Polo returned to Italy after his travels through China with news of a frozen creamed dessert. In Europe, ice cream could only be found in Italy. Then, in 1533, Italian noblewoman Catherine de'Medici of Italy married Henry II of France. As Queen, Catherine introduced ice cream to France. Soon, the popularity of the dessert spread across all of Europe.(4) The first recorded account of ice cream in the United States was in 1744. In a written letter, a guest of Maryland Governor William Bladen detailed a delicious frozen dessert featuring strawberries and milk. The invention of electricity and manufacturing meant that ice cream could be made and kept much more easily, and the popularity of the frozen treat grew quickly across the country.(5) To start, ice cream was served in a dish. It wasn't until the late 19th century that the ice cream cone made its first appearance. As with ice cream itself, there has always been some controversy over who the true inventor of the ice cream cone was. It is claimed that in 1896, a man by the name of Italo Marchiony invented the ice cream cone in New York City. He was granted a patent for this cup-shaped invention in 1903. Then, in 1904, ice cream was served in a true conical-shaped cone by Ernest Hamwi at the St. Louis World Fair. Whoever the true inventor was, the discovery caught on, and by 1924, Americans were eating over 200 million ice cream cones a year!Read the text "How Ice Cream Is Made":Ice cream is a frozen blend of sweetened cream and air with added flavoring. This is how it is made commercially.Necessary Ingredients:Dairy products, including milk, cream, and butter fatSugarEggsFlavoringApproved additives to prevent ice crystals during production processProduction Steps:Step 1: To start, the ingredients are carefully measured and then combined together. The dairy ingredients, solids, and additives are blended well to ensure the liquid and dry components are completely mixed.Step 2: Next, the mix is pasteurized. This means it is heated to high temperatures to remove any bacteria which could be found in the raw ingredients. Pasteurization can occur at 155F for 30 minutes or 175F for 25 seconds. The temperatures used to pasteurize ice cream need to be higher than those used for milk because the mixture includes high-fat dairy sources, sweeteners, and egg yolks.Step 3: Following pasteurization, the ice cream mix is homogenized. This occurs when the fat globules in the cream are broken down into smaller parts through vigorous mixing. Once homogenized, the ice cream should be very smooth and uniform, meaning free of bubbles. Now the ice cream will be easier to whip and will not melt as fast.Step 4: The next step is to let the ice cream mixture stand for at least four hours. During this time, the fat cools and forms crystals.Step 5: A special barrel freezer is then used to gradually freeze the ice cream. The machine also pumps clean air into the mix. This keeps the ice cream soft and allows it to absorb the different flavorings. Without the air, the mixture would become as hard as an ice cube.Step 6: During freezing, flavoring can be added. Ice cream flavors have moved on from plain vanilla and chocolate to include hundreds of combinations using fruit, nuts, candy, cookies, and other baked goods.Step 7: Finally, the ice cream is packaged and put into a blast freezer where the temperature is between -22 to -40 Fahrenheit.How does paragraph 4 of The History of Ice Cream relate to Step 7 of "How Ice Cream Is Made"? napthalene combustion can be used to calibrate the heat capacity of a bomb calorimeter The heat of combustion of naphthalene is -40.1kj/g.
