10 moles of helium is contained in a piston/cylinder device initially at a temperature T1 of 300 K and pressure P1 of 100kPa. The pressure applied to the piston is increased to P2, compressing the helium extremely rapidly to a final temperature T2 of 350 K. Helium may be treated as an ideal gas under these conditions, and CV for helium is equal to 1.5R. a) Calculate the final pressure P2 applied to the piston for this process b) Calculate the entropy generated within the gas due to the compression
