Question

A given mass of ideal gas is taken at constant pressure from state A (Pressure P, Volume V) to state B (Pressure P, Volume 4V). Subsequently, the gas is taken at constant volume from state B to state C (Pressure P/4, volume 4V). Select the correct statement(s) from the following:

TestHub · Accepted Answer

A→B isobaric expansion: T rises from T 0 ​ to 4 T 0 ​ , heat Q 1 ​ = n C P ​ ( 3 T 0 ​ ) is absorbed (A true). B→C isochoric: P falls from P to P /4 , so T falls from 4 T 0 ​ to T 0 ​ : heat Q 2 ​ = n C V ​ ( 3 T 0 ​ ) is rejected (B true). C P ​ > C V ​ ⇒ Q 1 ​ > Q 2 ​ (C true).
