An ideal monoatomic gas undergoes the process AB as shown in the figure. If the heat supplied and the work done in the process are `DeltaQ` and Delta W` respectively. The ratio `DeltaQ : DeltaW` is

A

`2. 50`

B

`1.67`

C

`0.67`

D

`0.40`

Text Solution

Verified by Experts

The correct Answer is:
A
`V prop T`
Isobaric Process
P = constant
`Q/W = Q/(Q - U) = (nC_p Delta T)/(n (C_P- C_V)Delta T) = C_P/(C_p - C_V) = (5/2 R)/R = 2.5`
