Newton's law of cooling states, "For a body cooling in a draft (i.e., by forced convection), the rate of
heat loss is proportional to the difference in temperatures between the body and its
surroundings." Since the temperature change  is proportional to the heat change
 |
(1) |
where m is the mass of the body and  is its heat capacity, we can write
 |
(2) |
where  is the derivative  of temperature with respect to time t,
 is the temperature
of the surroundings, and K is an experimental constant.
