Chapter 21 – Laws of Thermodynamics

In a thermodynamics process pressure of a fixed mass of a gas is changed in such a manner that the gas molecule give out 20 joule of heat and 10 joule of work is done on the gas. If the initial internal energy of the gas was 40 joule, then the final internal energy will [...]
