As liquid water freezes, what happens to its thermal energy?
A. Thermal Energy remains constant, and kinetic energy decreases.
B. Thermal energy remains constant, and potential energy decreases
C. Thermal energy decreases because kinetic energy is decreasing.
D Thermal energy decreases because potential energy is decreasing.
When the water freezes the kinetic energy decreases because it is staying in place instead of moving around, which also causes thermal energy to decrease.
