Lubricants by replacing sliding friction with fluid friction

Lubricant is used to reduce friction when replaced with fluid friction instead of sliding friction.

Explanation:

Lubricants reduce friction when replaced with fluid friction instead of sliding friction. Lubricant is used between surfaces which are in mutual contact this is used because it reduces friction between the two surfaces. Lubrication reduces heat developed in the moving parts.

This helps in removing debris from the surfaces. Mineral oils, synthetic oils, solid lubricants are used as lubricants. Lubricant acts as a 'seal' between the piston and the shaft which do not allow any gases from atmosphere.

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.
