1. Specific Latent heat

   • The energy needed for a substance to change shape.

2. Specific heat capacity

   • The amount of energy needed to warm 1 kg of a substance by 1 degree.

3. Measuring energy

   • Energy (J) = Voltage (V) X Current (A) X Time (S)

4. Conduction

   • When heat is passed through one molecule to another by its bond. Only works well in solids.

5. Convection

   • When fluid is heated it expands.This gets less dense than the cold fluid around it and hot particles rise,

6. Waves

   • Wave speed (m/s) = frequency (Hz) X wavelength (m)
   • The electromagnetic spectrum
     • How high or low the frequency and wavelength is
