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

Given: m is the mass of taken CO2 (m = 1 kg); T0 – initial abs. temperature (T0 = 268 K); T – final abs. temperature of carbon dioxide (T = 400 K).

Const: MCO2 – molar mass of carbon dioxide (MCO2 = 44.01 * 10-3 kg / mol); R – universal gas constant (R = 8.31 J / (mol * K)).

Solution:

We calculate the work done by the taken carbon dioxide using the formula: АСО2 = m * R * (T – T0) / МСО2.

Calculation: АСО2 = 1 * 8.31 * (400 – 268) / 44.01 ≈ 24.94 J.

Answer: The work done by the carbon dioxide taken is 24.94 J.
