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)

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)

For an ideal gas a) The change in internal energy in a constant pressure process from temperature T_(1) to T_(2) is equal to nC_(v) (T‌_(2)-T_(1)) , where Cv is the molar heat capacity at constant volume and n is the number of moles of the gas b) The change in internal energy of the gas and the work done by the gas are equal in magnitude in an adiabatic process c) The internal energy does not change in an isothermal process d) No heat is added or removed in an adiabatic process

For an ideal gas, (i) the change in internal energy in a constant pressure process from temperature T_1 to T_2 is equal to nC_V(T_2-T_1) , where C_V is the molar heat capacity at constant volume and n is the number of moles of the gas (ii) The change in internal enregy of the gas and the work done by the gas are equal in magnitude in an adiabatic process. (iii) The internal energy does not change in an isothermal process. ltbr. (iv) no heat is added or removed in an adiabatic process

Molar heat capacity at constant volume can be given as

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