What happens when a capillary tube of insufficient length is dipped in a liquid? Will the liquid overflow? |

Answer» Solution :We have `H=(2S0(Rrhog)` where R is the radius of curvature of the liquid meniscus. `HR=(2S)/(rrhog)` = a constant. So hR = h.R. Hence in a capillary tube of insufficient LENGTH, the liquid RISES to the top and spresds out to a new radius of curvature R. given by R. = hR/h.. The liquid will not overflow. |
