.152.50mol of an ideal gas with CV,m=3R/2 initially at a temperature Ti=298K and Pi=1.00 bar is enclosed in an adiabatic piston and cylinder assembly. The gas is compressed by placing a 650.kg mass on the piston of diameter 19.8cm. Calculate the work done in this process and the distance that the piston travels. Assume that the mass of the piston is negligible. First calculate the external pressure and the initial volume
