- 36. In a heat engine, what material can we "theoretically" use as the working substance? (a) Only an ideal gas (such as air), due to their thermodynamic properties. (b) We can use liquids but not solids, since liquids can conform to the shape of their containers (engine), but solids cannot. (c) Any material which expands upon heating can be used.10.-What is the heat of the isothermal process (from point B to point C)?27) Which of the following must be true for a thermodynamic process that starts and ends at the same state? A: The total heat and work for the cycle must both be zero B: The total work equals the heat C: The value of all state functions must be different at the beginning and the end of the process D: The change in internal energy over the whole cycle must equal 0 E: The temperature of the system will be constant throughout the process
