What kind of work does gas do with isobaric expansion from 2L to 3L. Gas pressure 140kPa.
| May 11, 2021 | education
Initial data: V1 (initial gas volume) = 2 liters (2 * 10 ^ -3 m3); V2 (gas volume after expansion) = 3 l (3 * 10 ^ -3 m3); P (gas pressure) = 140 kPa (140 * 10 ^ 3 Pa) = const (isobaric process).
The work that the gas will carry out is determined by the formula: A = P * ΔV = P * (V2 – V1).
Calculation: A = 140 * 10 ^ 3 * (3 * 10 ^ -3 – 2 * 10 ^ -3) = 140 J.
Answer: With isobaric expansion, the gas will do the work of 140 J.
