In an adiabatic expansion of the air, the volume is increased by 4%, what is the percentage change in pressure? (For air γ = 1.4)
A monoatomic gas of pressure p having volume V expands isothermally to a volume 2V and then adiabatically to a volume 16V. The final pressure of the gas is ____________.
`("ratio of specific heats" = 5/3)`
For an isothermal expansion of a perfect gas, the value of `(Delta "P")/"P"` is equal to ____________.
Assertion: Equal volumes of monatomic and polyatomic gases are adiabatically compressed separately to equal compression ratio `("P"_2/"P"_1)`. Then monatomic gas will have greater final volume.
Reason: Among ideal gases, molecules of a monatomic gas have the smallest number of degrees of freedom.
The work done on the system in changing the state of a gas adiabatically from equilibrium state A to equilibrium state B is 22.4 J.

( l cal = 4.2 J)
