Question

STATE WHETHER The statements are TRUE OR FALSE please specify 1. Consider stirring a cake mix with an electric mixer. This is an adiabatic process that is irreversible because the energy stored within the system cannot be spontaneously released in a manner to cause the mass of the system to turn the paddle wheel in the opposite direction to do work on the surroundings. ( TRUE OR FALSE)? 2. When the compression process is non-quasi-equilibrium, the molecules before the piston face cannot escape fast enough, forming a high-pressure region in front of the piston. It takes more work to move the piston against this high-pressure region. Hence, a non-quasi-equilibrium compression process requires a larger work input than the corresponding quasi-equilibrium one. ( T/F) 3. A reversible expansion or compression process cannot involve unrestrained expansion or sudden compression, and thus it is non-quasi-equilibrium. (T/F) 4. A quasi-equilibrium expansion or compression process involves external irreversibilities (such as heat transfer through a finite temperature difference) and thus is irreversible. (True or False)
