Why are rain drops spherical? |
|
Answer» Yeah you are a genius!!! Rain drops are not spherical they are hemispherical like a paper weight because of the force of air from the bottom . To know more search factomania sony BBC earth water drop shape on YouTube This answer is perfect and understandable. Thank you. We all know that for a given volume of a liquid, a sphere has the least surface area. Also, the more the surface area of an object, the more is its surface energy.\xa0Now, to remain in stable equilibrium, a body always tries to minimize its surface energy. Therefore it tries to reduce its surface area and hence acquires a spherical shape.\xa0All this phenomena is because of the presence of surface tension of a fluid.\xa0 |
