Spring 2018 Calculating work. A gas is enclosed in a cylinder fitted with a light piston that moves without friction. This piston always exerts a constant, atmospheric pressure on the gas so that the pressure within the gas is constant, atmospheric pressure. 4. Sketch a plot of pressure vs. volume in this situation. To do this, you can plot points. What is the pressure of the gas when the volume is 12.0 m? 18.2 m? When 1250 kJ of heat...
