Question

12. The molecules in a material need to move with more energy for the material to change from a

A. liquid to a gas.
B. gas to a liquid.
C. liquid to a solid.
D. gas to a solid.

Answer 1

A) liquid to a gas

Step-by-step explanation:

When molecular motion increases, the space between molecules increases, and when it decreases, the space between molecules decreases. It requires energy for a solid to melt into a liquid, and once a liquid is changing state to a gas, potential energy is increasing during that phase change.
