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? What is the change in entropy of mercury vapor (Lv = 2.7 x 105 J/kg) when 0.50 kg of it condenses to a liquid at its boiling point of 357 oC? A quantity of an ideal gas undergoes an isothermal expansion at 20 oC and does 3.0 x 103 J of work on its surroundings in the process. (a) Will the entropy of the gas (1) increase, (2) remain the same, or (3) decrease? ...If an engine does 200 J of net work and exhausts 800 J of heat per cycle, what is its thermal efficiency?
