If heat engine A absorbs more heat than heat engine B from a hot reservoir, will engine A necessarily do more net work than engine B? Explain your reasoning.
Answer to relevant QuestionsThe maximum efficiency of a heat engine is 1 (or). Can the COP of a thermal pump be greater than 1? Explain. An ideal gas initially at temperature To, pressure po, and volume Vo is compressed to one-half its initial volume. As shown in Fig. 12.20, process 1 is adiabatic, 2 is isothermal, and 3 is isobaric. Rank the work done on the ...An ideal gas sample expands isothermally by tripling its volume and doing 5.0 x 104J of work at 40 oC. (a) How many moles of gas are there in the sample? (b) Was heat added to or removed from the sample, and how much? During a liquid-to-solid phase change of a substance, its change in entropy is – 4.19 x 103 J/K. If 1.67 x 106 J of heat is removed in the process, what is the freezing point of the substance in degrees Celsius? Suppose that the system described by the T–S diagram in Fig. 12.25 is returned to its original state, state 1, by a reversible process depicted by a straight line from state 3 to state 1. (a) The change in entropy of the ...
