  • Different materials have different specific heat capacities
  • More energy needs to be transferred to the thermal energy store of some materials to increase their temperature than others
  • Materials that need to gain lots of energy in their thermal energy stored to warm up also transfer lots of energy when they cool down again. They can 'store' a lot of energy
  • Specific heat capacity is the amout of energy needed to raise the temperature of 1kg of a substance by 1°C
  •  ∆E(J) = m(kg)c(J/kg°C)∆θ(°C)
  • Change in energy(J) = mass(kg) x specific heat capacity(J/kg°C) x temperature change(°C)
