10. The work done by a piston is measured to be 1000 J. If the pressure is a constant 1000 Pa, what is the change in volume of the piston? 11. Is the process described in #10 isovolumetric ? Explain . 12. Is it possible for a substance to change temperature in an isovolumetric and adiabatic process? Explain. 13. A substance is heated with 1000 J and does 700 J of work on the atmosphere. What is the change in internal energy of the substance? 14. An engine causes a car to move 10 meters with a force of 100 N. The engine produces 10,000 101 energy. What is the efficiency of this engine
