Laplace’s Law of Spherical Membrane

Science > Physics > Surface Tension > Laplace’s Law of Spherical Membrane In this article, we shall study Laplace’s Law about the excess of pressure inside a drop or a bubble of a liquid. Excess of Pressure Inside a Drop of a Liquid and Soap Bubble: Due to surface tension, free liquid drops and bubbles […]

Capillary Action or Capillarity

Science > Physics > Surface Tension > Capillary Action A capillary tube is a tube with a very fine bore. The phenomenon of a rise and fall of a liquid inside a capillary tube when it is dipped in the liquid is called capillary action or capillarity. When a glass capillary is immersed in water, […]
