Mixing of Gases: Pressure in Connected Cylinders

In summary, when gases are mixed in connected cylinders, the pressure will equalize throughout the system regardless of the initial pressures of each gas. This is affected by factors such as the amount of gas, volume of the cylinders, and temperature. The pressure can be calculated using the ideal gas law, and as the volume increases, the pressure decreases. The mixing of gases in connected cylinders is similar to the mixing of liquids, but gases are more compressible and have a larger range of pressures.

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
 

1. How does the pressure of gases change when they are mixed in connected cylinders?

When gases are mixed in connected cylinders, the pressure of the gases will equalize throughout the system. This means that the pressure will be the same in all connected cylinders, regardless of the initial pressures of each gas.

2. What factors affect the pressure of gases in connected cylinders?

The pressure of gases in connected cylinders is affected by the amount of gas in each cylinder, the volume of the cylinders, and the temperature of the gases. These factors determine the number of gas molecules present and their kinetic energy, which contribute to the overall pressure.

3. Can the pressure of gases in connected cylinders be calculated?

Yes, the pressure of gases in connected cylinders can be calculated using the ideal gas law, which states that the pressure of a gas is directly proportional to the number of gas molecules, temperature, and volume of the container.

4. What is the relationship between pressure and volume in connected cylinders?

In connected cylinders, as the volume of the cylinders increases, the pressure of the gases will decrease. This is because the same amount of gas molecules are spread out over a larger volume, resulting in fewer collisions and a lower pressure.

5. How does the mixing of gases in connected cylinders compare to the mixing of liquids?

The mixing of gases in connected cylinders is similar to the mixing of liquids, as both involve the equalization of pressure throughout the system. However, gases are more compressible and have a larger range of pressures, whereas liquids are not compressible and have a more limited range of pressures.
