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

Surface tension is due to

Unit .of surface tension of a liquid :

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

In an experiment to determine the surface tension of water by capillary rise, water rises to a height of 0.03m in a capillary tube of diameter 10^-3 m. If the angle of contact is negligibly small, calculate the surface tension of water.

Why is the surface tension concept held for liquids only and not for gases?

Why the solubility of alkyl halide in water is very low?

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?

What is the impact on surface tension when (/) impurity is increased, and (//) temperature is decreased?

State the dimension and unit of surface tension.
