4.3.2 Internal energy and energy transfers

State that the internal energy of a system is stored in the atoms and molecules that make up the system
Explain that internal energy is the total kinetic energy and potential energy of all the particles in a system
Calculate the change in thermal energy by applying but not recalling the equation [∆E =m c ∆θ ]
Calculate the specific latent heat of fusion/vaporisation by applying, but not recalling, the equation: [ E = mL ]
Interpret and draw heating and cooling graphs that include changes of state
Distinguish between specific heat capacity and specific latent heat
