In an adiabatic expansion of an ideal gas

In an adiabatic expansion of an ideal gas.

In an adiabatic expansion of an ideal gas the product of pressure and volume .

The ratio of specific heats of a gas in 1.40 . There are 200 moles of gas initially present. The gas undergoes adiabatic expansion and as a result which, the temperature of the gas falls from 400 K to 100 K. Give R=8.312J "mole"^(-1) K^(-1) . Calculate the amount or work done by the gas on the surroundings.

In an isothermal expansion of an ideal gas

During adiabatic expansion, the increase in volume is associated with
