Heat transfer is thermal energy in transit due to a spatial temperature difference – The greater the difference in temperature between an object and its surroundings the greater the heat transfer rate will be. Newton’s Law of Cooling – The law states that the rate of change of the temperature of an object is proportional to the difference between its initial temperature T 0 and the ambient temperature T a at time t.
