Determine the work done by 1 kg of carbon dioxide with isobaric heating from 268 to 400 K.

Data: m (mass of carbon dioxide) = 1 kg; T1 (initial temperature of carbon dioxide) = 268 K; T2 (temperature of carbon dioxide after isobaric heating) = 400 K.

Reference data: R (universal gas constant) = 8.31 J / (mol * K); M (molar mass of carbon dioxide) = 0.044 kg / mol.

The work that carbon dioxide will do during isobaric heating is calculated by the formula: A = P * ΔV = (m / V) * R * ΔT = (m / M) * R * (T2 – T1).

Calculation: A = (1 / 0.044) * 8.31 * (400 – 268) = 24 930 J.
