Question 5 • Physics in the Universe

Read the problem. A container with water is sealed and pressurized. Initially, the water pressure at the bottom of the container is measured at 3000 Pa. What would happen to the pressure at the bottom if the depth of the water is increased?

Answer
A
The pressure would remain the same.
B
The pressure would decrease.
C
The pressure would become zero.
D
The pressure would increase.

Explanation

Pressure in a liquid increases with depth because the water lower down supports the weight of more water above it. Since the water’s depth is increased, the pressure at the bottom would increase above its initial value of 3000 Pa. Therefore, the correct choice is D, “The pressure would increase.”
