... Considerations of Carnot cycles led to various rigorous macroscopic statements of the second law, that can be shown to be equivalent: Clausius: It is impossible to devise an engine which, working in a cycle, produces no effect other than the transfer of heat from a colder to a hotter body. Kelvin: I ...

... Q1-a: Assume that at very low temperature, the molar heat capacity of copper is equal to ( 7x10-4 T ) J K-1 mole-1 , where T is the absolute temperature. Show that if ( 10-7 ) J of heat is added to a mole of copper, which is initially at the absolute zero, the temperature of the copper rises to (0.0 ...
