"Entropy change" negative will? Prove using the relevant equations. (Only verbal answer will not be accepted. It will be proved as thermodynamic calculations under relevant equations). (a) Air isothermally expanded from 6 bar pressure to 3 bar pressure (b) Compressing the air to half its volume at constant pressure (c) constant volume control of air until the pressure is threefold (d) Air expansion isentropically from 6 bar pressure to 3 bar pressure

A sketch of set of four processes involved in a closed thermodynamic system is shown in the adjoining pressure- volume diagram. Isothermal expansion brings 220 grams of a fluid from 415 kPa to a final pressure of 115 kPa and specific volume of 120 litres/kilogram. A reversible cooling process takes place at constant pressure with a work done of 525 Joules and then followed by a constant volume until the pressure of the fluid becomes 62 kPa. A Polytropic compression...
