Engineers design devices like Ipads and cellphones to cool down quickly so they do not overheat. What happens to the molecules in an Ipad when the temperature of the Ipad decreases?

Alana is cooking rice in a pot. When she leaves the pot on the stove for a while, the temperature of the rice increases. What happens to the molecules of the rice when the temperature of the rice increases?

When you reduce the temperature of a sample from 100 degrees Celsius to 30 degrees Celsius , the molecules move faster because they have more kinetic energy.

Amy and Payton are camping and have potatoes wrapped in foil to eat. Payton put her potato in the campfire for a while, but Amy did not. Now Payton’s potato has a high temperature. What is the difference between the molecules of the two potatoes?

When something heats up, it moves faster, and when it cools down, it moves slower.
