Answer» <p>Surface tension is the elastic tendency of a fluid surface which makes it acquire the least surface area possible.</p><p>Factors affecting :</p><p># Viscosity</p><p># The surface tension of a liquid decreases with increase in temperature.</p><p># when charge is given to a soap bubble, its size increases surface tension of liquid decreases due to electrification.</p><p># surface tension decreases when partially soluble impurities either on the surface or dissolved in it. Such as:- soap, detergent, phenol etc. are added in water.</p><p># surface tension increases when highly soluble impurities such as salt is added in water.</p><p># At boiling point surface tension of liquid becomes zero at freezing point it becomes maximum.</p>
