For this problem and all others, I strongly recommend that you follow the 5+1 method, outlined in Lecture 2: Draw and label the system List assumptions Identify governing equation Reduce governing equation based on assumptions Solve for unknown(s) +1: sanity check

4.6 Consider a gas in a cylinder at room temperature with a volume of 0.065 m*. The gas is confined by a piston with a weight of 100 N and an area of 0.65 m*. The pressure above the piston is 1 atm. a. What is the pressure of the gas in the cylinder? b. The gas is heated by an external source. To maintain a constant pressure, the piston moves up, expanding the volume of the gas. If the volume occupied by the gas doubles, how much work has the gas done
