1. State the first Law of thermodynamics. 2. What is meant by the mechanical equivalent of heat. 3. What are the values and units for the mechanical equivalent of heat in the various systems. 4. What is meant by a heat engine? 5. Solids and liquids have only one specific heat, but gases have two. Why? 6. State the second law of thermodynamics. 7. What is meant by an isobaric process? What is an adiabatic process? 8. Briefly describe the Joule's method of determining the mechanical equivalent of heat. 9. When is heat added to a system not equal to the increase in the internal energy of the system. 10. Besides actually adding heat to a system, in what way may the temperature of the system be increased? 11. On what factors does the efficiency of a heat engine depend
