Question

why is the surface tension of psints snd lubricating oils kept low?​

Answer 1

Answer:

Surface tension of oil and paint kept low,so that they can be spread over a large surface area. due to this reason,surface tension kept as low for large spreading. Answer: ... The surface tension of the lubricating oils and paints is kept low because it can spread over large area easily and faster.

Answer 2

Explanation:

Because paints and lubricating are responsible for reducing the force of friction. so, the body has lubricated then their surface has lower tension.
