Differentiate between liquid pressure and atmospheric pressure.
Difference between liquid pressure and atmospheric pressure
Liquid pressure | Atmospheric pressure |
1. The pressure at a point in a liquid is caused by the weight of the liquid overlying a unit area. | 1. The pressure at a point in the air is caused by the weight of the air overlying a unit area. |
2. Liquid pressure varies with the depth of liquid. | 2. Atmospheric pressure varies with the altitude. |
3. Liquid pressure is directly proportional to the density of the liquid. | 3. Atmospheric pressure decreases with increases in altitude. |
