Answers

Answer 1

Answer:

Both types of waves transfer energy

Explanation:

I think that's right

Answer 2

Electromagnetic waves and sound waves  both types of waves can transfer energy.

What are electromagnetic waves?

The electromagnetic radiation consists of waves made up of electromagnetic field which are capable of propogating through space and carry the radiant electromagnetic energy.

The radiation are composed of electromagnetic waves which are synchronized oscillations of electric and magnetic fields . They are created due to change which is periodic in electric as well as magnetic fields.

In vacuum ,all the electromagnetic waves travel at the same speed that is with the speed of air.The position of an electromagnetic wave in an electromagnetic spectrum is characterized by it's frequency or wavelength.They are emitted by electrically charged particles which undergo acceleration and subsequently interact with other charged particles.

Olaf the snowman has a mass of 38 kg, and a body temperature of -4.2 degrees Celsius. He took a sip of hot coffee with a volume of 15 mL and a temperature of 80.0 degrees Celsius. The coffee turned into ice and eventually become a part of Olaf. Determine the final temperature of Olaf.

Answers

Answer:

84.2 degrees

Explanation:

Olaf the snowman has an heat capacity of ice while the coffee can be

assumed to have the same heat capacity of water.

The final temperature of ice is approximately -4.08 °C

Reasons:

The heat lost by the coffee = The heat gained by Olaf...(1)

ΔQ = m₁·c₁·(T₃ - T₁) = m₂·c₂·(T₂ - T₃)

Mass of the snowman, m₁ = 38 kg

Initial temperature of the snowman, T₁ = -4.2°C

Volume of coffee, V = 15 mL = 0.000015 m³

Initial temperature of the coffee = 80.0 °C

Specific heat capacity of the snowman, c₁ = 2.097 J/(g·°C)

Specific heat capacity of the coffee, c₂ = 4.187 J/(g·°C)

Latent heat of fusion of the coffee into ice = 334 J/g

Density of the ice, ρ₂ = 997 kg/m³

Solution:

Mass of the coffee, m₂ = 0.000015 m³ × 997 kg/m³ = 0.014955 kg = 14.955 grams

Heat given to convert the coffee to ice = 334 J/g × 14.955 g = 4,994.97 J

Heat given to cool the coffee to 0°C = 14.955×4.187×80.0 = 5009.3268

Heat given to cool the coffee to 0°C = 5,009.3268 J

Heat given to reduce the temperature of the coffee turned to ice is

presented as follows;

Heat to cool frozen coffee = 14.955 × 2.108 × T₃ = 31.52514·T₃

Heat gained by Olaf = m₁·c₁·(T₃ - T₁) = 38,000× 2.097 × (T₃ - (-4.2))

Which from equation (1) gives

4,994.97 + 5009.3268 + 31.52514·T₃ = 38,000× 2.097 × (T₃ - (-4.2))

Solving with a graphing calculator, gives;

T₃ ≈ -4.08 °C

The final temperature of Olaf, T₃ ≈ -4.08 °C

If 0.484J of heat is added to 0.1372g of water, how much will the temperature increase?

0.263 °C
0.927 °c
0.843 °C
0.460 °C

Answers

Answer:

ΔT = 0.843 °C

Explanation:

Given data:

Heat added = 0.484 J

Mass of water = 0.1372 g

Temperature increase = ΔT = ?

Solution:

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

Specific heat capacity of water is 4.184 j/g.°C

Now we will put the values in formula.

0.484 j = 0.1372 g × 4.184 j/g.°C× ΔT

0.484 j = 0.574j/°C× ΔT

ΔT = 0.484 j / 0.574j/°C

ΔT = 0.843 °C

1 You place a 28.95-g piece of gold in a 10-ml graduated cylinder. The level of the water rises 1.50 mL. What is the density of gold?​

Answers

Answer:

What mass of silver will raise the level of the water in the graduated cylinder 1.50 mL? (Ans) 28.95 g / 1.50 mL = 19.3 g/mL (The gold's density)

19.3 gm/ml³ is the density of gold  .

What do you mean by the density of the substance?

Density, mass of a unit volume of a material substance. Density of a substance tells how close the particles of a substance are packed.

The formula for density is D = M/V, where d is density, M is mass, and V is volume.

Density is commonly expressed in units of grams per cubic centimeter.

The SI unit of density is kilogram per cubic meter (kg/m3).

It is also represented  in the c g s unit of grams per cubic centimeter (g/cm3).

To calculate density of gold (here):

Given,

Mass of gold=28.95 gm

Volume of water=1.50 mL

Density=?

Density =Mass/Volume

Density=28.95/1.50

Density=19.3 gm/ml³

Hence, 19.3 gm/ml³ is the density of gold .

How are oxidation states of transition metals indicated in the names of metal
compounds?
A. Prefixes are used to indicate oxidation states.
B. Group numbers are used to indicate oxidation states.
C. Roman numerals are used to indicate oxidation states.
D. Subscripts are used to indicate oxidation states.

Answers

Answer:

The anser is c

Roman numerals are used to indicate oxidation states. Hence, option C is correct.

What is the oxidation state?

An oxidation state is a number given to the atom of an element when participating in a chemical reaction.

Roman numerals are used to indicate oxidation states of transition metals.

The names for transition metal compounds often have roman numerals in them, because the roman numerals indicate the charge on the transition metal. But the oxidation state of Cu in CuO is +2, and the oxidation state of Cu in [tex]Cu_2O[/tex] is +1. Name metal first and charge and transition metal with a roman numeral.

The transition metals may form more than one ion, thus it is needed to be specified which particular ion we are talking about. This is indicated by assigning a Roman numeral after the metal. The Roman numeral denotes the charge and the oxidation state of the transition metal ion.

[tex]Fe^{2+}[/tex] would be named iron (II) and [tex]Fe^{3+}[/tex] would be named iron (III).

Hence, option C is correct.
