A heating element of resistance r is fitted inside an adiabatic cylinder which carries a frictionless piston of mass in and cross-section A as shown in diagram. The cylinder contains one mole of an ideal diatomic gas. The current flows through the element such that the temperature rises with time t as DeltaT = alphat + 1/2beta t^2 ( alpha and beta are constants), while pressure remains constant. The atmospheric pressure above the piston is P_0 . Then the rate of increase in internal energy is 5/2 R (alpha + beta t) the current flowing in the element is sqrt(5/(2r)(alpha +betat)) the piston moves upwards with constant acceleration the piston moves upwards with constant speed
