One mole of a gas mixture is heated under constant pressure, and heat required Q is plotted against temperature difference acquired. Find ghe value of `gamma` for mixture.

A

`3/4`

B

`1/4`

C

`3/2`

D

`2/3`

Text Solution

Verified by Experts

The correct Answer is:
C
`Q = DeltaU+W = nf/2RDeltaT+nRDeltaT`
`Q = (1+f/2)RnDeltaTimplies 2500/100 = ((1+f)/(2))Rimplies f = 4`
`gamma=1+2/f = 3/2`.
