Asample of ice is heated continuously until it becomes a liquid, and then a gas. its temperature is recorded throughout and a graph is constructed. during the transition from solid ice to liquid water the graph is flat indicating no increase in kinetic energy even though heat is still being added to the sample. what does this section represent?
a. the specific latent heat of vaporization
b. the specific heat
c. the specific latent heat of fusion
d. the internal energy

The answer to your question is: C. The specific latent heat of fusion

Explanation:

A. The specific latent heat of vaporization  Specific latent heat of vaporization indicates the transition from liquid to vapor, but we are not looking for this definition. This answer is wrong.

B. The specific heat indicates the amount of heat needed to increase the temperature of water 1°C, so this answer is wrong.

C. The specific latent heat of fusion . This heat indicate the transition from solid ie to liquid, so this is the right answer.

D. The internal energy measures the energy of the molecules of a substance, so this answer is wrong.

The answer to your question is: C. The specific latent heat of fusion

Explanation:

14 days is the half-life of phosphorus-32
