Explain why
Surface tension of a liquid is independent of the area of the surface

Unit .of surface tension of a liquid :

Surface tension is due to

Is friction independent of actual area of contact.

What is surface tension of a liquid ? Show that the surface tension of a liquid is numerically equal to the sueface energy per unit area.

The surface tension of a liquid decreases with temperature. True or False?

. The surface tension of liquid is 70 dynes/cm. It may be expressed in MKS as

The total surface area of the solid cylinder is 462cm^2 .If the area of the curved surface of the cylinder is one-third of the total surface area,then find the volume of the cylinder.

Surface tension of all lubricating oils and paints is kept low. Why?

Explain why Vapour pressure of a liquid is constant at constant temperature.

Explain why Vapour pressure of a liquid decreases when a non-volatile solute is added to it.
