Change in internal energy of an ideal gas is given by `DeltaU=nC_(V)DeltaT`. This is applicable for (`C_(V)`=molar heat capacity at constant volume)

When an ideal gas undergoes an adiabatic change causing a temperature change DeltaT (i) there is no heat ganied or lost by the gas (ii) the work done by the gas is equal to change in internal eenrgy (iii) the change in internal energy per mole of the gas is C_(V)DeltaT , where C_(V) is the molar heat capacity at constant volume.

For an ideal monoatomic gas, molar heat capacity at constant volume (C_(v)) is

The molar heat capacity of an ideal gas in a process varies as C=C_(V)+alphaT^(2) (where C_(V) is mola heat capacity at constant volume and alpha is a constant). Then the equation of the process is

For certain process the molar heat capacity of an ideal gas is found to be (C_v+R/2) , where C_v is the molar heat capacity of the same gas at constant volume. For the given process, it can be concluded that
