Question

A jar is completely filled with water, and then it is sealed with a lid. If you push down on the lid with a pressure of 1000 Pa, what happens to the water pressure at the bottom of the jar? The water pressure at the bottom of the jar depends on the height of the jar. The water pressure at the bottom of the jar will increase by 1000 Pa. The water pressure at the bottom of the jar will increase by less than 1000 Pa. The water pressure at the bottom of the jar remains unchanged. The water pressure at the bottom of the jar will increase by more than 1000 Pa

Answer 1

The water pressure at the bottom of the jar will increase by 1000 Pa.

Step-by-step explanation:

The Pascal principle states that:

In a fluid, a change in pressure at any point in the fluid is transmitted equally throughout the fluid, as it is occuring everywhere.

If we apply this principle at the case mentioned in the problem, we can say that:

- An initial pressure of 1000 Pa is applied on the top of the fluid (the water)

- According to Pascal's law, this pressure is transmitted with equal intensity (1000 Pa) to every point of the fluid

- So, the water pressure at the bottom of the jar will also increase by the same amount, 1000 Pa
