An ideal gas is filled in an insulated cylinder fitted with a movable piston connected with an ideal spring (of force constant K) as shown in the figure. Initially, the spring is relaxed and the gas in the piston has volume V0 and temperature T0 . Now the gas in the cylinder is heated slowly so that the piston slides towards right to a distance x. Find the final pressure and temperature of the gas. (Given atmospheric pressure = P0 and area of cross-section of the cylinder is A). |
