define pascal`s law?

Pascal’s Law:

The law states that when there is an increase in pressure at any point in a confined fluid, there is an equal increase at every other point in the container.

In the given container as shown there is an increase in pressure as the length of the column of liquid increases due to the increased mass of the fluid above it.

P3 would have higher value of pressure as there is highest level of fluid above it.

Basically it it means that fluid that is in a container or confined space will expand into every possible space if it is put under pressure. An example of this would be if you were to squeeze a balloon that is filled with liquid soap. The soap will stretch the balloon any way that is possible in order to spread into the allowable space.
