Identify the following gas compression descriptions as adiabatic, isothermal or isobaric.
a. As the gas compresses, the internal energy ÄU, decreases when the temperature decreases; the work done on the gas is greater than the heat removed from the gas: ___________________
b. As the gas compresses, both ÄU and temperature of the gas increase as work is done on the gas; no heat is lost or gained by the gas during the process: _______________________
c. As the gas compresses, the heat removed from the gas is equal to the work done on the gas; ÄU is equal to zero and the temperature of the gas remains constant throughout the process: ________________________________
b. is adiabatic (no heat in or out)
c. is isothermal (constant T)
a. can be isobaric (compression as heat is removed to maintain constant P), but does not have to be.
