A student tries to cool his dormitory room by opening the refrigerator door. Will that work? Explain.
Answer to relevant QuestionsIf 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. In an isobaric process, an ideal gas sample can do work on the environment but its temperature also increases. How can this be? A monatomic ideal gas (y = 1.67) is compressed adiabatically from a pressure of 1.00 x 105Pa and volume of 240 L to a volume of 40.0 L. (a) What is the final pressure of the gas? (b) How much work is done on the gas? A process involves 1.0 kg of steam condensing to water at 100 oC. (a) The change in entropy of the steam (water) is (1) positive, (2) zero, (3) negative. Why? (b) What is the change in entropy of the steam (water)? A quantity of ideal gas goes through an isothermal process and does 400 J of net work. (a) The internal energy of the gas is (1) higher than, (2) the same as, (3) less than when it started. Why? (b) Is a net amount of heat ...
