This condition of equality of pressure on either side of a movable wall is a state of mechanical equilibrium between the two gases. p1= p2版权所有：华东理工大学物理化学教研室 26 Mechanical equilibrium Two gases are in separate containers that share a common movable wall The stage when the two pressures are equal and the wall has no further tendency to move.
