Pressure in liquids

Question 1

What happens in pressure in liquids?

Answer 1

When an object is immersed in a fluid, the fluid will exert pressure, squeezing the object
This pressure is exerted evenly across the whole surface of the fluid and in all directions
The pressure exerted on objects in fluids creates forces against surfaces
These forces act at 90 degrees (at right angles) to the surface

Question 2

What is the formula for pressure?

Answer 2

Pressure= height x density x gravitational field strength

p = pressure in pascals (Pa)
h = height of the column in metres (m)
ρ = density of the liquid in kilograms per metre cubed (kg/m3)
g = gravitational field strength on Earth in newtons per kilogram (N/kg)
The force from the pressure is exerted evenly across the whole surface of an object in a liquid, and in all directions
