Physics · Unit 1 · Heating processes · Kinetic particle model and specific heat capacity
Explain that the change in the internal energy of a system is equal to the energy added or removed by heating plus the work done on or by the system, and recognise this as the first law of thermodynamics and that this is a consequence of the law of conservation of energy.
