27
Q

what energy change releases energy to make your body hot?

A

exothermic

when you exercise, you sweat, which makes you hot – this is an example of what energy change?

A

exothermic

30
Q

what is deposition?

A

when gas changes to solid without going through the liquid phase first, it goes straight through
