evaporating is a kind of phase change & condensing is a kind of phase change ->  evaporating and condensing are both phase change  evaporating and condensing are both phase change & temperature changing can cause phase changes ->  evaporating and condensing can both be caused by temperature changing  evaporating and condensing can both be caused by temperature changing & temperature is a measure of heat energy -> evaporating and condensing can both be caused by the change of heat energy
