when we solve questions regarding an open vessel having gas fielled and then some part of it expelled out etc.. in my it is giving that in an open vessel pressure and volume remains constant.. but i think PV=nRT p is the pressure of gas and and volume of the gas(or the container) then why we assume pressure to be constant if even if some gas is expelling out..please explain the the individual terms of ideal gas equation..i.e pressure, volume etc . are these of gasor of surrounding???
