Chapter 15 - The Laws of Thermodynamics - Questions: 8

Answer

a. The high-temp reservoir is the combustion chamber. The low-temperature reservoir is the area outside. b. The high-temp reservoir is the boiler. The low-temperature reservoir is where water condenses.

Work Step by Step

a. The high-temperature reservoir is the burning gas–air mixture in the cylinder. Strictly speaking, this isn’t a heat reservoir because the temperature isn’t constant. The low-temperature reservoir is the outside of the engine, where the exhaust is expelled. b. There are different kinds of steam engines, and different answers, but in the type used in steam locomotives the high-temperature reservoir is the firebox. Strictly speaking, this isn’t a heat reservoir because the temperature isn’t constant. The low-temperature reservoir is the environment where the steam is vented.
