Final answer:
The pressure on the first floor of a building is always less than the pressure of water on the ground floor due to the increase in pressure with depth in a fluid.
Step-by-step explanation:
The pressure on the first floor of a building is always less than the pressure of water on the ground floor due to the increase in pressure with depth in a fluid. This is because the pressure in a fluid near Earth varies with depth, and as you go deeper into the fluid, the weight of the fluid above increases, resulting in higher pressure.
An example of this is the pressure in a swimming pool. As you dive deeper into the pool, the pressure increases because water is much denser than air. The weight of the water above you and the atmosphere contributes to the increase in pressure. Therefore, the pressure on the first floor of a building is always less than the pressure of water on the ground floor because the first floor is at a shallower depth compared to the ground floor.
