Explain chemical energy store

• Energy on object has because of its temperature (the total kinetic and potential energy of the particles in the object)

• Energy that can be transferred by chemical reactions involving foods, fuels, and the chemicals in batteries

• Energy a magnetic object has when it is near a magnet or in a magnetic field

• Energy stores in the nucleus of an atom

Explain thermal energy store

• Energy an object has because of its temperature (the total kinetic and potential energy of the particles in the object)

What is a closed system

• Where no energy can escape or enter from surroundings

• Where electric can build up on a system

• Where all energy can escape from surroundings

• Object or group of objects
