Question 10 • Physical Science

Which takes place as water cycles from the bottom of the pot toward the top?

Answer
A
Water molecules gain kinetic energy.
B
Water molecules gain thermal energy.
C
Thermal energy is transferred.
D
Chemical energy is transferred.

Explanation

Water at the bottom of the pot warms and rises, carrying energy with it. This movement transfers thermal energy from the warmer water near the bottom toward the cooler water above—a process called convection. The best choice is “Thermal energy is transferred.”
