How does pressure in liquid change?

Pressure in a liquid increases with depth due to the weight of the liquid above. This increase in pressure can be described by the hydrostatic pressure formula: ( P = P_0 + \rho g h ), where ( P ) is the total pressure, ( P_0 ) is the atmospheric pressure at the surface, ( \rho ) is the density of the liquid, ( g ) is the acceleration due to gravity, and ( h ) is the depth. As you go deeper, both the weight of the liquid column and the pressure it exerts increase. Additionally, pressure in a liquid is transmitted equally in all directions, a principle known as Pascal's law.
