1A heat engine does 320 J of work, as it takes 700 J heat from gasoline. What is the internal energy change? 2 The internal energy of a turbine increases by 280 J when it does 185 J of work. How much heat did turbine take?
3. The gas sample in the frictionless cylinder-piston system expands. It takes 175 J of heat energy. The mass of the piston is 50 kg. What is the internal energy change of the gas during the process?
