In an industrial process, a gas phase refrigerant reduces its internal energy by 70 kJ by means of a propeller that, when rotating, provides it with 20 kJ. At the same time, the gas expands by pushing a piston that travels 10 cm with which said fluid performs a expansion work of 100 kJ. How much energy is transferred as heat during the process? A) 10 kJ B) – 190 kJ C) 50 kJ D) 150 kJ
