Chapter 1 Thermodynamics
... According to Carnot’s theorem the efficiency of reversible process between any two temperatures is a universal number, i.e. ÷(T1 , T2 ). This allows us to define not only relative, but also absolute temperature scale. Consider three Carnot cycles 1-2, 2-3 and 1-3 operating between different temperat ...

... Since ice absorbs energy as it melts, we can measure this energy. Melting energy is called the heat of fusion,Hfus, for ice. (The name comes from the fact that to fuse two pieces of metal you must melt them.) You will melt a known amount of ice and see how much heat it absorbs. Heat of fusion is re ...
