Question

Which of the following correctly describes what happens to the kinetic energy of water when it changes from the liquid

state to the solid state?
• There is no change in the kinetic energy of the molecules.
• The kinetic energy of the molecules increases.
• The kinetic energy of the molecules increases then decreases.
O The kinetic energy of the molecules decreases.

Answer 1

The kinetic energy of the water decreases

Step-by-step explanation:

Kinetic energy is simply motion. If a liquid moves it is because it has kinetic energy but a solid such as ice can't move so the kinetic energy is lesser. Comparing the trend between these two shows that kinetic energy decreases.
