Statement 1: An ideal gas compressed adiabatically by a constant external pressure equal to its final pressure ends at a higher temperature than when compressed reversibly and adiabatically to the same pressure.
Statement 2: The work done on the gas is larger in the irreversible compression, and all of it appears as increase in internal energy.
Options:
Answer:
A
Solution:
q=0 so Δ U=w. Irreversible compression needs wirr>wrev (II correct), hence a larger Δ U and Δ T and a higher final T: I correct. II explains I. Answer (a).
