Is lubricating oil a volatile liquid?
No lubricating oils are not. The reason is that they have to be able to withstand heat from friction of moving engine parts etc. They have very high boiling points and thus very low volatility.
Of all the nonmetals which has the highest conductivity?
The carbon allotrope we call diamond has the highest thermal (heat) conductivity of any material. It is far better an any metal (or anything else we know of) at allowing heat to pass through it. It is carbon (in its graphite allotrope) that has the highest electrical conductivity under normal conditions of any of the nonmetals. Any metal is a better electrical conductor, but carbon is good enough to make brushes for electrical motors out of. You'll recall that the brushes complete the electrical circuit between the wiring of the non-moving elements to the rotating commutator.
What does moving randomly mean?
It means that you have no particular pattern as to which you move, you are moving without any meaning as to why you are moving or how you are moving
How can you determine the direction in which a comet is moving?
You determine it by were is it moving and when a bright streek is moving
Is chyme a slow moving or fast moving liquid?
It's a slow moving semiliquid.
Why lubricating oil is used?
Lubricating oil is used to reduce friction between moving parts and to prevent damage due to excess heat. Lubricating oil also carries away sludge preventing the erosion of moving parts.
How does lubricating machinery-such as the chain on your bike reduce friction?
The surface tension between the metal on your chain pieces is high. The surface tension is low on lubricants like oil or graphite so putting them between moving surfaces provides a opposing surface for both materials that has a low friction.
What does lubricating oil do?
Reduces friction between moving parts.
What do the lubricating and the cooling systems do in your car?
They keep the engine and all the other moving parts from scraping together and going kaboom from overheating. The lubricating system primarily keeps the moving parts from rubbing each other too much.
Why is lubricating oil put on moving parts of a machine?
So they dont stick and like expload!
Why are guards fitted to machinery?
To protect people from getting hurt by moving, sharp or hot pieces of machinery.
Why should excessive vibration not be allowed to continue in moving parts of machinery?
Unnecessary wear and stress will shorten the lifespan of the moving parts and machinery in general if vibration is allowed to continue.

What is an example of reducing friction is important in the moving parts of machinery?
friction is a force which opposes the direction of the movement of a certain body. reducing the friction between moving parts will lead to an increase of acceleration or speed of that particularly body.
Name the force that exists between the moving parts of a machine and how can this be reduced?
Friction. It can be reduced by lubricating substances such as oil.
What will stop the moving parts of a bicycle from going rusty?
Lubricating them with products such as WD-40. It's something which needs to be done regularly.
