WebIn a heat engine 4 mol of an ideal gas consisting of molecules of 6 degrees of freedom goes through a cycle ABCDA consisting of the following steps: 1. A → B: starting at a pressure of PA = 5 atm and temperature 646 K, the volume VA is doubled isothermally; 2. B → C: the gas is expanded adiabatically until the pressure is 1 atm; 3. WebThey are naturally present in the atmosphere in the form of carbon dioxide and gaseous oxygen. Because they're always circulating between the soil, the air, and the water, living matter's constantly renewed. Atmospheric oxygen comes mainly from green plants.
