The gas volume changes from Vp to Va at constant temperature T. The cartoon on the right shows a piston of gas undergoing this
compression while submerged in a container of room temperature water, which acts as a reservoir.
The initial state of this process is a piston containing 2 moles of a monatomic gas at T, = 293 K (room temperature water) and volume Vh =
1.0 m3. The gas is compressed until Va = 0.2 m. During the compression, the heat bath of room temperature water maintains the
temperature of the gas at T.= 293 K.
Calculate the work done in joules by the gas during this process.
Do not include units in your answer.
Be careful to use the standard sign convention for work done by the gas.
Write your numerical answer in normal form as described above in the instructions to this worksheet.

Compressing air to fill a scuba tank warms it up. A dive shop compensates by putting the tank in a tub of water, keeping the tank and the gas inside it at a constant temperature as it is filled. If the system is the tank, what are the signs of W and Q for this process? What can you say about the relative magnitudes of W and Q?
-70 J of work are done on the gas in the process shown in
(Figure 1).
