Isothermal compression and isothermal expansion
Thread Content
What do isothermal compression and isothermal expansion mean? Can someone explain it? Thank you
Isothermal compression: Compression while maintaining a constant temperature. According to the formula PV=nRT, the internal energy of the substance remains constant during this process; the energy obtained during compression is released to the outside environment in the form of heat. Isothermal expansion: Expansion outward while maintaining a constant temperature. During this process, the temperature remains constant and the internal energy remains constant. The loss of work done on the outside world is compensated by absorbing heat from the surrounding environment.
