Question 11 • IA-Chemistry A Survey of Chemistry A

Melting can be best described as a process in which molecules

Answer
A
lose kinetic energy and move slowly.
B
lose kinetic energy and remain stationary.
C
gain kinetic energy and escape into the atmosphere.
D
gain enough kinetic energy to get past each other.

Explanation

During melting, a solid absorbs heat, and its particles gain energy. They gain enough kinetic energy to move past one another while still remaining close together as a liquid. “Escape into the atmosphere” describes particles leaving a liquid during evaporation, not melting.
