Determine what work the gas did during isobaric expansion under a pressure of 0.25 MPa, if its volume changed by 10 liters.
| April 26, 2021 | education
Initial data: P (constant gas pressure) = 0.25 MPa (0.25 * 10 ^ 6 Pa); ΔV (change in gas volume during isobaric expansion) = 10 liters (10 dm3; 10 * 10 ^ -3 m3).
The work that the gas could do during isobaric expansion can be calculated by the formula: A = P * ΔV.
Calculation: A = 0.25 * 10 ^ 6 * 10 * 10 ^ -3 = 2500 J (2.5 kJ).
Answer: Gas has done work 2.5 kJ.
