Revise AQA GCSE Physics 3.2 Internal energy and energy transfers with the question bank and revision guides.
Energy is stored inside a system by the particles (atoms and molecules) that make up the system. This is called internal energy. • Internal energy is the total kinetic energy and potential energy of all the particles (atoms and molecules) that make up a system. • Heating changes the energy stored within the system by increasing the energy of the particles that make up the system. This either raises the temperature of the system or produces a change of state.
