Students should be able to:
- describe internal energy as an energy store that is made up of the total kinetic energy associated with the random motion of the particles and the total potential energy between the particles in the system
- define heat capacity and specific heat capacity
- recall and apply the relationship energy transfer (by heating) = mass × specific heat capacity x change in temperature to new situations or to solve related problems
- describe melting/solidification and boiling/condensation as processes of energy transfer without a change in temperature
- explain the difference between boiling and evaporation
- define latent heat and specific latent heat
- recall and apply the relationship energy transfer (by heating for a change of state) = mass × specific latent heat to new situations or to solve related problems
- explain latent heat in terms of behaviour of particles in a body
- sketch and interpret a cooling curve.
