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.

GC-1 An ideal gas is sealed in a cylinder and compressed
by exerting a force on the piston as shown to the
right. When the piston is stationary, the force on
the shaft is 400N and the length L of gas in the
cylinder is 15.0cm and the gas is at 20.0°C. Neglect
friction between the cylinder and the piston.
a) Draw the free body diagram for the piston and
apply Fnet ma to the horizontal direction. Think
about the direction of the force of the outside air
on the piston.

b) Use your equation from part a) to get an equation
for the pressure in the gas (remember that P=F/A).
c) Use your equation from b) to calculate the pressure in the gas in the cylinder in N/m².
d) Find the number of moles of gas in the cylinder.
400N
e) The cylinder (and gas) are now heated to 400°C while the 400N force is maintained on the piston
shaft. Find the new distance L of the piston from the end of the cylinder.
