One mole of CO_(2) at 300 K and1 atm pressure is heated in a closed vessel so that temperature is 500 K is pressureis 5 atm. Then it is cooled so that temperature is 300 K and pressure is 1 atm. What is the change in internal energy of the gas ?

1.	One mole of CO_(2) at 300 K and1 atm pressure is heated in a closed vessel so that temperature is 500 K is pressureis 5 atm. Then it is cooled so that temperature is 300 K and pressure is 1 atm. What is the change in internal energy of the gas ?
Answer» SOLUTION :No CHANGE because internal ENERGYIS a state function and the SYSTEM has returned to ORIGINAL state.
