Why use lubricant?

Answer 1

All matter is made of molecules. Solids, liquids, and gases. Solid matter molecules are closer together and more rigid. When solids rub together they will create heat and remove surface molecules from each other. To allow machines to operate, with solid surfaces rubbing against each other, and not tearing each other's molecules away, most often liquids are used, like oil or water, to keep the solid surfaces apart from each other. The fluid will also disperse some of the heat that is generated too. Once you start studying the effects of different liquids that are used as lubricants, you will be amazed at the diversities each offer.

Answer 2

It is not necessary to use lubricant. Most women in their teens and early 20's and 30's don't need lube as heavy petting and kissing causes the glands in the vagina to secrete natural lubricant to make intercourse possible. However as a woman ages and especially after menopause, an additional lubricant becomes desirable if not a necessity.

Answer 3

a simple ans is that lubrucants reduces friction

Answer 4

Lubricants are used to reduce friction. There are many different lubricants used in cars for example to keep the parts running for the longest amount of time.

Answer 5

lubricant is used to reduce friction .it so enhances the performance of an engine

Answer 6

Lubricants reduce friction, which makes the machines more energy efficient and makes them last much longer. Excess heat could melt the machine parts.

Answer 7

Oil. Grease
