Temperature Transfer • 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 T0 and the ambient temperature Ta at time t.
