In an isobaric process, `Delta Q = (K gamma)/(gamma - 1)` where `gamma = C_(P)//C_(V)`. What is ` K`?

Options

A. Pressure
B. Volume
C. `Delta U`
D. `Delta W`

Answer

D

Explanation

d. `Delta Q = (K gamma)/(gamma - 1) = (KC_(P) // C_(V))/((C_(P)//C_(V)) - 1) = (KC_(P))/(C_(P) - C_(V))`
`= (K (n C_(P) Delta T))/((n C_(P) Delta T - nC_(v) Delta T)) = (K Delta Q)/((Delta Q - Delta U)) = (K Delta Q)/(Delta W)`
or `1 = (K)/(Delta w) implies K = Delta W`
