The Volume V of a monoatomic gas varies with its temperature T, as shown in the graph. The ratio of work done by the gas, to the heat absorbed by it, when it undergoes a change from state A to state B, is
  1. 13
  2. 23
  3. 25
  4. 27

Solution

VT
Isobaric process
W=PV=nRT
Q=nCPT
For mono atomic gas f = 3
CP=f2R+R=52R
So WQ=nRTnCPT=25 ~
