When you rub your hand together, you produce a little heat. describe the flow of energy that causes the heat to be produced. use terms chemical energy, kinetic energy, friction, and heat in your answer.

Your hands rubbing together causes the molecules to bump into each other, this is friction. As the molecules bump into each other they begin to move faster, and the fast movements of the molecules is what creates heat.
