In a vertical cylinder with a capacity of V = 200 cm3 under a heavy piston there is gas at a temperature T = 300 K. The mass of the piston is m = 50 kg, its area is S = 50 cm2. To increase the temperature of the gas by ΔT = 100 K, it was given an amount of heat Q = 46.5 J. Find the change in the internal energy of the gas. Atmospheric pressure p0 = 1.0 • 105 Pa. Ignore friction. Acceleration of free fall g is taken equal to 10 m/s2.
