66. Go Two Carnot air conditioners, A and B, are removing heat fromdifferent rooms. The outside temperature is the same for both rooms,309.0 K. The room serviced by unit A is kept at a temperature of 294.0 K,while the room serviced by unit B is kept at 301.0 K. The heat removedfrom either room is 4330 J. For both units, find the magnitude of the workrequired and the magnitude of the heat deposited outside.

When gasoline burns in an automobile engine, the heat released (336 J) causes the products CO2 and H2O to expand, which pushes the pistons outward. Excess heat is removed by the car’s cooling system. If the work associated with the expanding gases is equal to 463 J, how much is the change in internal energy of the piston?
