State the laws of liquid pressure.
1) Liquid pressure is the same in all directions about a point in a liquid.
2) In a stationary liquid, the pressure is the same at all points on a horizontal plane.
3) Pressure at a point inside the liquid increases with depth from the free surface.
4) Pressure at the same depth is different in different liquids. It increases with an increase in the density of the liquid.
5) A liquid seeks its own level.
