Question

moles of a diatomic perfect gas are allowed to expand at constant pressure. The initial volume and temperature are V 0 ​ and T 0 ​ respectively. If 2 7 ​ R T 0 ​ is transferred to the gas as heat then the final volume and temperature are:

TestHub · Accepted Answer

Isobaric: Q = n C P ​ Δ T = 10 × 2 7 R ​ × Δ T = 2 7 ​ R T 0 ​ ⇒ Δ T = 10 T 0 ​ ​ . T f ​ = 1.1 T 0 ​ and V ∝ T at constant pressure ⇒ V f ​ = 1.1 V 0 ​ .
