Systems at constant pressure

Postby 004624886 » Sun Jan 17, 2016 3:05 pm

If a questions says a system is at constant pressure, that would mean that volume is changing, would that mean that we can assume internal pressure = external pressure?

I don't think it matters if the internal pressure is equal to the outside pressue, all that matters is that when it says pressure is constant it means that for the system that you're working with, the pressure of that system is constant. Atleast I think that's the only thing you can assume from that statement. If internal and external pressure actually mattered, I don't think you can assumed they are equal, just that the system's pressure is.
