A hypothetical gas expands adiabatically such that its volume changes from 08 litres to 27 litres. If the ratio of final pressure of the gas to initial pressure of the gas is1681 . Then the ratio of CpCv will be.
  1. 43
  2. 31
  3. 12
  4. 32

Solution

Let γ be the ratio of CpCv.

Then for adiabatic process PVγ =Constant

⇒PiPf=VfViγ

⇒8116=278γ⇒32343=278γ

⇒γ=43
