Q. With the increase of temperature, the surface tension of the liquid

ManipalManipal 2010

Solution:

Surface tension is the energy that is required to stretch the surface of liquid one incremental amount of area. This requires an input of energy, that is surface tension is positive. It is easier to stretch the surface of a liquid the warmer it gets, because the molecules at the surface are hopping around more, the higher the temperature is. Hence, surface tension always decreases with rise in temperature.
