A girl takes some ice cream out of the freezer. What happens to the speed of the molecules in the ice cream when it is taken out of the freezer.
They speed up.
500
What is the thermal energy of the paint bucket outside?
90
500
Why do things that have more molecules take longer to heat up and cool down?
Because they energy has to spread out over more molecules
