Imagine some helium in a cylinder with an initial volume of 1 liter and an initial pressure of 1 atm. Somehow the helium is made to expand to a final volume of 3 liters, in such a wat that its pressure rises in direct proportion to its volume.

  1. Sketch a graph of pressure vs. volume for this process
  1. Calculate the work done on the gas during this process, assuming there are no “other” types of work being done.
  1. Calculate the change in the helium’s energy content during this process.
  1. Calculate the amount of heat added to or removed from the helium during this process.ETHR

e. Describe what you might do to cause the pressure to rise as the helium expands.

    To practice Problem-Solving Strategy 19.1 Work in Ideal-gas Processes. A cylinder with initial volume V contains a sample of a gas at pressure p. On one end of the cylinder, a piston is let free to move so that the gas slowly expands in such a way that its pressure is directly proportional to its volume. After the gas reaches the volume 3V and pressure 3p, the piston is pushed in so that the gas is compressed isobarically to its...
