Example
Assume there are two systems with the same mass and specific heat. System A has an average temperature of 500 kelvins and system B has an average temperature of 400 kelvins. If thirty seconds after the systems are put in contact they both reach 450 K, then the average rate of heat flow is:
50 J/30 s, or rather 1.66 W.
(note: specific heat and masses = 1)

Famous quotes containing the word example:
“Our intellect is not the most subtle, the most powerful, the most appropriate, instrument for revealing the truth. It is life that, little by little, example by example, permits us to see that what is most important to our heart, or to our mind, is learned not by reasoning but through other agencies. Then it is that the intellect, observing their superiority, abdicates its control to them upon reasoned grounds and agrees to become their collaborator and lackey.”
—Marcel Proust (1871–1922)
