I don't know why they said the gas pressure was constant (you didn't give the context with respect to the solution) because it doesn't have to be to solve the problem. You only need to apply the first law.The work done by the gas is always based on the external pressure. If the process is quasistatic and involves no friction, then it is also reversible and generates no entropy. But that involves the second law and is not needed to solve the problem | |
