A diatomic gas, having C P = 7 2 R and C V = 5 2 R , is heated at constant pressure. The ratio d U : d Q : d W

Question

A diatomic gas, having C P = 7 2 R and C V = 5 2 R , is heated at constant pressure. The ratio d U : d Q : d W, 3 : 5 : 2, 5 : 7 : 3, 5 : 7 : 2, 3 : 7 : 2

MARKS App · Accepted Answer

d U = n C v d T ⇒ d Q = n C p d T ⇒ d W = P d V = n R d T (isobaric process) d U : d Q : d W : C v : C p : R = 5 R 2 : 7 R 2 : R = 5 : 7 : 2 .
