Which of the following best describes the heat of fusion?

Question

Group of answer choices

the amount of potential energy necessary for a phase change to gaseous form

the lowest temperature at which the particles are able to exist in the liquid form

the temperature at which the particles have sufficient molecular motion to exist in the form of a gas

the potential energy absorbed by a solid as it changes to a liquid

Answer 1

The best description of the heat of fusion is:

"the potential energy absorbed by a solid as it changes to a liquid."

The heat of fusion refers to the energy required to change a substance from solid to liquid at its melting point without changing its temperature.
