Question: 1 / 400

How does water pressure change with depth in a container?

It remains constant regardless of depth

It increases with greater depth

Water pressure in a container is influenced by the depth of the water above a given point. As you move deeper into the water, the weight of the water above exerts greater pressure on the water below. This is due to the fact that pressure is defined as force per unit area, and in the case of a fluid, the force results from the gravitational pull on the mass of the fluid. Therefore, as depth increases, the accumulation of water creates an increase in pressure.

This principle is fundamental in fluid mechanics and is often summarized by the equation for hydrostatic pressure, which states that pressure at a given depth is equal to the density of the fluid multiplied by the gravitational acceleration and the depth. As such, deeper levels in the fluid experience higher pressure, leading to the conclusion that as one descends in a container filled with water, pressure consistently increases with greater depth.
