Acylindrical container of a fixed volume is divided into three sections, si, s2, s3. the sections s1 and 52 are separated by an adiabatic piston, whereas the sections s2 and s3 are separated by a heat-conducting piston. the pistons can slide along the walls of the cylinder without friction. each section of the cylinder contains 1.00 mol of a perfect diatomic gas. initially, the gas pressure in all three sections is 1.00 bar and the temperature is 298 k. the gas in s1 is heated slowly until the temperature of the gas in s3 reaches 348 k. find the final temperature, pressure and volume, as well as the change of internal energy for each section. determine the total energy supplied to the gas in si. 9. solve the previous problem for the case where both pistons are (a) adiabatic and (b) heat-conducting
