What work was done by air with a mass of 200 g when it was heated isobaric by 20 K. What amount of heat was reported to it?

From the condition of the problem, we are given the mass of air and the change in temperature during the isobaric process. Isobaric heating implies that the process was carried out at constant pressure. The released amount of heat can be found by the formula Q = cm (t1-t2), where from air = 1005 J / kg * K (tabular value), Next, we find the change in internal energy according to the formula, where M air = 0.029 kg / mol (tabular value). The work is found from the first law of thermodynamics. A = Q-change U
