Force exerted on per unit area is called pressure. Pressure is related with area on which it is applied. When the area is increased the pressure exerted is less. But when the area on which pressure is exerted is decrease the pressure increases. So, we can conclude that pressure increases with decrease in area. List the characteristics of pressure exerted by a liquid.
  • Liquid exerts pressure in all directions.
  • Pressure in liquid does not depends on shape, size and surface area of the container.
  • Pressure increases with depth.
  • All points at the same level in a liquid are at the same pressure.
  • Pressure does not depend on the surface of the immersed object.
