Heat loss by any route may be expressed in the general equation
H = kA(Tc−Ta).
where H is the loss in Joules/s, k is the cooling constant, A is the surface area, and Tc–Ta is the difference between coffee temperature and air temperature.
it takes about 4 joules of heat for the temperature of one gram of water to increase by 1 degree centegrade.
