Temperature & Heat: Heat Capacity

Heat The energy due to movement of molecules within a body Scalar quantity Joules (J) Heat transfer occurs from areas of higher temperature to areas of lower temperature N.B. Heat is not the same as temperature

Heat Capacity Amount of heat required to raise the temperature of a body by 1 K Scalar quantity Joule per kelvin (J/ K)

Q = CΔθ Q = Energy C = Heat capacity of body Δθ = Change in temperature

Specific Heat Capacity Amount of heat required to raise the temperature of 1 kg of a substance by 1 K Scalar quantity Joule per kilogram per kelvin (J / kg/ K)

Q = mcΔθ m = Mass of body c = Specific heat capacity
