poor conductors of heat

Front 17

gas

Back 17

evaporation is the process of lliquid changing to a gas

Front 18

condenstation

Back 18

opposite of evaporation; droplets of fluid begin to bulid up on a substance such as hot vapor when hot vapor gets rid of mosts its heat

Front 19

forces

Back 19

solid molecules have more attractive _____ than liquids or gases

Front 20

temperature

Back 20

a rise in _______will cause a change in the motion of it molecules, will cause a change in kinetic energy, and will cause a change in the heat content of the molecules

convection

Back 25

hot air ballons traveling into air with inside air decreasing density and rising over cooler more dense air
