1. What?
   1. Specific Heat capacity
   2. Amount of heat needed to change temp of 1kg of substance by 1 kelvin
2. EG
   1. Water
      1. 4200
      2. highest
         1. transferring heat
            1. central heating
            2. coolant
   2. Seawater
      1. 3900
   3. Ice
      1. 2100
   4. Lead

3. Maths
   1. The Heat Equation
      1. Q = mcΔθ
         1. Q = Number of joules
         2. m = Mass of substance
         3. c = specific heat capacity
         4. Δθ = Increase in temp
4. Heat lost = Heat gained
