Since the tank is insulated so the process will be isothermal and the temperature of the gas will remain constant throughout the process.
Apply first law of thermodynamics
where is the change in internal energy, Q and W are the heat and work done respectively.
Internal energy depends on the temperature so the change in internal energy would be zero if the temperature is constant in an isothermal process. So , so the equation (1) becomes
