During one complete cycle of a heat engine process, which of the following quantities is nonzero?   a. The change in internal energy   b. The change in volume.   c. The work done   d. The change in pressure   e. The change in temperature

Study Guide Mix n Match:       Heat is Energy moving from low temperature to high temperature. Energy moving from high temperature to low temperature. The same as temperature.       The First Law of Thermodynamics defines The principle of entropy. The Law of heat addition. The conservation of heat.         The greater the difference in temperature between the input                         reservoir and the output reservoir of a heat engine, the Greater the efficiency. Less the efficiency. Efficiency is not affected by temperature.           A Carnot engine Can never be 100% efficient. Can sometimes be 100% efficient. Is always 100% efficient.         When a water is going through a phase change from liquid to gas It gives up 540 cal/g of heat. It absorbs 540 cal/g of heat. It makes a 100oC temperature change.          Displacement is a Scalar Quantity Vector Quantity MKS Quantity        The acceleration at the peak of the rise of a projectile is Equal…

Which of the following statements about a heat engine must be true?   i) Energy is taken in from a cold source and expelled to the hot source  ii) Even an ideal heat engine with no energy loss due to non-conservative forces has an    efficiency lower than 100%   iii) The internal energy of a heat engine must always increase after the process is    complete  iv) The heat engine cannot do more work than the energy taken in A) ii, iii B) ii, iv C) i D) i, ii E) i, iv

One of the consequences of the 2nd Law of Thermodynamics is:   A. You can get the same amount of energy out of a process as you put in   B. Two bodies are in thermal equilibrium when they have the same temperature   C. You can get more energy out of a process than you put in   D. The starting and finishing temperature of a cycle must be the same   E. You can not get as much energy out of a process as you put in
