1. A Carnot heat engine and an irreversible heat engine both operate between the same high temperature and low temperature reservoirs. They absorb the same energy from the high temperature reservoir as heat. The irreversible engine: A. transfers more energy to the low temperature reservoir as heat. B. cannot absorb the same energy from the high temperature reservoir as heat without violating the second law of thermodynamics. C. has the greater efficiency. D. does more work. E. has the same efficiency as the reversible engine. 2. Heat is: A. energy transferred by virtue of a temperature difference. B. energy transferred by macroscopic work. C. energy content of an object. D. a property objects have by virtue of their temperatures. E. a temperature difference. 3. The energy given off as heat by 300 g of an alloy as it cools by 50 C° raises the temperature of 300 g of water from 30° C to 40° C in an insulated container. The specific heat of the alloy (in cal/g · C°) is: A.
