Mixing of Gases: Pressure in Connected Cylinders

[its_thepip]

Hi

Suppose there are two cylinders / vessels.
In one cylinder the pressure is 1.5 bar & in other 0.5 bar.If both cylinder are connected internally through valve connection, what will be the final pressure in both? explain

You did not mention if the two cylinders are of the same capacity. If so, the pressure is 1.0 bar in both provided that the temperature is unchanged.

Let the two cyclinders have different diameters, D and d
