In a vertical cylinder under the piston there is 29 g air. What work will the air do when the temperature rises by 100 K?

To find out the amount of work of air in the cylinder, we will use the formula: A (isobaric heating) = ν * R * ΔT = m * R * ΔT / Mair.

Const: R – universal gas constant (R = 8.31 J / (mol * K)); Mair – average molar (average) mass of air (Mair = 28.98 * 10-3 kg / mol).

Data: m – air mass (m = 29 * 10-3 kg); ΔT – change (increase) in temperature (ΔT = 100 K).

Calculation: A = m * R * ΔT / Mair = 29 * 10-3 * 8.31 * 100 / (28.98 * 10-3) = 831.6 J.

Answer: Air should have done work in 831.6 J.
