1. The problem statement, all variables and given/known data A cylinder with a 16-cm-diameter piston contains gas at a pressure of 3.0 atm. A.How much force does the gas exert on the piston? B.How much force does the environment exert on the piston? C.The gas expands at constant pressure and pushes the piston out 10 cm. How much work is done by the environment? D.How much work is done by the gas? 2. Relevant equations P=F/A=N/m^2 W=Fd 3. The attempt at a solution A. F=(.08^2)(pi)(3)(1.013e5)=6110 N [Correct] B. F=(.08^2)(pi)(1)(1.013e5)=2040 N[Incorrect] C. [Unable to calculate due to part B] D. W=(6110)(.1)=611 J[Correct] Isn't 1 atm the pressure of the enviroment? Any help would be appreciated.
