Surface tension is the ability of a liquid to act as a stretched elastic skin which is formed by the bonds between and among the molecules of the liquid. When the temp. of the liquid is increased, these bonds gradually break up and the stretched elastic skin becomes weaker, hence, the surface tension is reduced. That is why boiling or heating is one of the ways of reducing surface tension in liquids.
It decreases simply becoz...wen their is increase in temperature of the liquid...der will be an increase in the entropy(the degree of orderliness...or disorderliness of a system) and this increase in entropy will cause the molecules of the liquid disperse, theereby causing partial or no relatively surface tension on the liquid. I rest my case.
Its A. Cos d impurities will b removed wen heated nd will decrease d surface tension.
surface tension is the form of a fluid behaving like an elastic streched body, therefore why it is reducing is because when heat is applied to a liquid it loses its surface tension power and gets less viscost.
surface tension is the force of attraction between the molecules of a fluid making the surface of the fluid like a stretched elastic skin. when the temperature of the fluid is increased gives the molecules of the fluid kinetic energy to break loose from that chain or bond holding them and thereby decreasing the surface tension of the fluid.
A is correct bcos when temp. Increases it makes d water molecules vibrates vigorously and then shrinks d tension acting parallel 2d surface of d liquid
It's 'A' bcos d force in d water surface dat tends 2 trap d water molecule in d container wil b weak bcos d temperature is increased wen heat is applied derby allowing d water molecules 2 escape by evapourating. D heat den break those tension down wich makes d force dat trap d water molecules weak
