A tank of argon gas has a volume of 0.0160 m3. The gas has a pressure of 5.00 atm and a temperature of 293 K. How much argon is in the tank? The tank is fitted with a piston and the gas is allowed to expand isothermally until its pressure is 3.00 atm. Subsequently, the pressure drops to 1.00 atm at constant volume. Find the final temperature and volume of the gas. How much work was done by the gas? Graph the pressure versus volume of the gas for this two-step process. The graph may be drawn, but use a ruler and correctly measure the distance between points along both the P and V axes.
