Document Summary
Most hand warmers work by using the heat released from the slow oxidation of iron. The amount your hand temperature rises depends on several factors: Mainly, the amount of heat released by the reaction. Even though chemistry is the study of matter, energy affects matter. Energy is anything that has the capacity to do work. Work is a force acting over a distance. Heat is the flow of energy caused by a difference in temperature. Energy can be exchanged between objects through contact. You can think of energy as a quantity an object can possess. You can think of heat and work as the two different ways that an object can exchange energy with other objects. Kinetic energy is energy of motion or energy that is being transferred. Thermal energy is the energy associated with temperature. Thermal energy is a kind of kinetic energy.
