Task id16204

In a vertical cylinder under a heavy piston there is oxygen with a mass m = 2 kg. To increase the temperature of oxygen by dT = 5 K, it was given an amount of heat dQ = 9160 J. Determine the specific heat of oxygen c, the work it does during expansion, and the increase in its internal energy dU. Molar mass of oxygen c = 0.032 kg/mol.
