Chemical energy: plants use chemical energy when they convert the light into food (aka break it down into sugars)
Heat energy: Animals use heat energy so they wont freeze, by forming heat energy they will either be active (running, so on) or be somewhere that the sun hits them so that their bodies will convert the sunlight into heat
Electrical energy: Humans use electrical energy for just about everything like the lights, making food, using electronics, etc.
False. Think about how teachers have air conditioners on the top of the windows and how air balloons float up!! Therefore warm hair is lighter then cold air.
