Energy Temperature and Heat
Energy is power derived from the use of physical or chemical resources. Energy is especially used to provide light and heat or to work machines. Heat (or, thermal energy) is directly related to temperature. While we cannot see individual atoms vibrating, we can feel their kinetic energies as temperature. When there’s a difference between the temperature of the environment and a system within it, thermal energy is transferred between them as heat. Using water as an example, if there is a transfer of energy from hot water to cold water, the flow of energy is called heat. Heat can be defined as a flow of energy due to a temperature difference. Using these concepts, students recognize and categorize chemical reactions where heat flows out of a system (exothermic reaction), and where heat moves into a system (endothermic reaction).
