A cylindrical container having nonconducting walls is partitioned in two equal parts such that the volume of the each parts is equal to V_(0). A movable nonconducting piston is kept between the two parts. Gas on left is slowly heated so that the gas on right is compressed upto volume (V_(0))/(8). Find pressure and temperature on both sides if initial pressure and temperature, were P _(0) and T_(0) respectively. Also find heat given by the heater to the gas. (number of moles in each part is n)
