Chapter 19: Q. 5 (page 543)
500 J of work must be done to compress a gas to half its initial volume at constant temperature. How much work must be done to compress the gas by a factor of 10, starting from its initial volume?
The value of work done energy is 1661J

A beaker with a metal bottom is filled with of water at . It is brought into good thermal contact with a container holding of a monatomic gas at pressure. Both containers are well insulated from their surroundings.
What is the gas pressure after a long time has elapsed? You can assume that the containers themselves are nearly massless and do not affect the outcome.
You would like to put a solar hot water system on your roof, but you're not sure it's feasible. A reference book on solar energy shows that the ground-level solar intensity in your city is for at least 5 hours a day throughout most of the year. Assuming that a completely black collector plate loses energy only by radiation, and that the air temperature is , what is the equilibrium temperature of a collector plate directly facing the sun? Note that while a plate has two sides, only the side facing the sun will radiate because the opposite side will be well insulated.
You come into the lab one day and find a well-insulated thermos bottle containing of boiling liquid nitrogen. The remainder of the thermos has nitrogen gas at a pressure of atm. The gas and liquid are in thermal equilibrium. While waiting for lab to start, you notice a piece of iron on the table with " " written on it. Just for fun, you drop the iron into the thermos and seal the cap tightly so that no gas can escape. After a few seconds have passed, what is the pressure inside the thermos? The density of liquid nitrogen is .
Two containers hold equal masses of nitrogen gas at equal temperatures. You supply 10 J of heat to container A while not allowing its volume to change, and you supply 10 J of heat to container B while not allowing its pressure to change. Afterward, is temperature TA greater than, less than, or equal to TB? Explain.
How much work is done on the gas in the process shown in Figure EX19.1?
