An ideal gas with pressure volume and temperature expanded isothermally to a volume to be
Answers
Answer:
the isothermal compression of a gas there is work done on the system to decrease the volume and increase the pressure. Doing work on the gas increases the internal energy and will tend to increase the temperature. To maintain the constant temperature energy must leave the system as heat and enter the environment.The area under pv diagram gives the work done on the gas between initial state i and final state f. Here p is the pressure and dV is the change in volume. (1) In the process 1, the work done W1 will be zero for vertical path. ... (2) For the process 2, work done is negative of the area under the curve.These processes describe the relationship between internal energy of a system and its changes. The main difference between isothermal and adiabatic process is that isothermal process occurs under constant temperature whereas adiabatic process occurs under varying temperature.The Joule expansion (also called free expansion) is an irreversible process in thermodynamics in which a volume of gas is kept in one side of a thermally isolated container (via a small partition), with the other side of the container being evacuated
