13- Gas in a cylinder sealed by a sliding piston, receives 39.9 kJ of heat and expands by 0.2 m' against an atmospheric pressure of 1 bar, while an energy losses due to friction between the piston and the cylinder is 5 kJ. Through a lever mechanism actuated by the piston, a mass of 50 kg is also raised through 10 m. Find the change of internal energy of the gas.
