Heating and internal energy
Heating and internal energy
Heating is the transfer of energy from a higher-temperature region to a lower-temperature region. It is a transfer pathway, not an energy store, so an object does not “contain heat”.
Step-by-step lessons on Edexcel GCSE Physics 14.2 Specific heat capacity and latent heat, covering 14.2.1 Heating, temperature and changes of state, 14.2.2 Specific heat capacity and specific latent heat, 14.2.3 Specific heat capacity calculation, 14.2.4 Specific latent heat calculation, and 14.2.5 Reducing energy transfer through thermal insulation. Each one builds up to exam-style questions. Master the required practical work and core equations early, since both papers can draw on content and maths skills from across the whole specification.
