Mechanical Engineering

Consider 50 moles of carbon dioxide in a piston-cylinder that isisothermally compressed at temperature of T=350 K from 100 kPa to400 kPa. What are the changes in the total entropy (of theUniverse), the system, and the surroundings if the gas iscompressed using a heat reservoir at a temperature of 350 K? Usinga heat reservoir at a temperature of 250 K? You can assume that theprocesses within the piston-cylinder system are internallyreversible.
