What is the difference between pure substance and mechanical mixture and solutions?
1. A pure substance can not be separated farther since it is composed of one type of atom. 2. I can't define mechanical mixture... Check your text book 3. A solution is one or more substances. I can: As she said a pure substance has only one type of particle. A solution is MORE then one substance. But in a solution u can't see the different parts. In a mechanical mixture, there is more then one particle like in a solution, but u can see the different particles.

How do mechanical pencils work?
Mechanical pencils work by using a mechanism to extend a thin lead refill as you write or draw. The lead is held in place by a clutch mechanism that allows it to move in and out of the pencil tip. When you press down to write, the lead is extended, and when you release the pressure, the lead retracts back into the pencil.
Why it is wrong to say lead pencil 'lead pencil'?
Because there is no lead in them any more.
Is 0.5 lead a number 2 pencil?
0.5 lead may or may not be equivalent to a #2 pencil. #2 refers to the hardness of the lead, while numbers referring to mechanical pencil leads such as 0.5mm and 0.7mm refer to the width of the lead. 0.5mm lead will be finer and likely more prone to breaking, but can allow much finer lines to be drawn. 0.7mm lead will usually be slightly more resistant to breakage, but will have thicker lines.
How long is a mechanical pencil eraser in inches?

What are differences between pencils and mechanical pencils?
Correct Answer:This all depends on how often each is used, and the care given to each.If both are used on a daily basis, the pencil would last longer as the leads within the mechanical pencil would eventually run out before the wooden one would be sharpened down to its eraser.Typically a mechanical pencil holds eight to ten leads in the inner chamber, while one is within the exiting chamber. As this lead comes to its end it will either be used up until the exiting chamber can no longer hold onto it (and the next lead is coming up behind it), or it will annoy the user by slipping back up into the chamber as the next lead has not found its way into the exiting chamber.When the final lead is nearly finished it will either fall on out or continually frustrate the user by slipping back into the exiting chamber. More lead can be bought for a mechanical pencil, which would mean that essentially the mechanical pencil will last longer than a typical wooden pencil.The problem with this theory is that not all mechanical pencils are made the same. Some manufacturers make their mechanical pencils in such a way that they cannot be reused either because the lead is not a typical universal size, they do not manufacture refill lead, and they may not make it possible to even open the mechanical pencil to replace the lead. In any one of these three cases, this makes the standard wooden pencil last longer.The other deciding factor on which will last longer is up to the user. The person using a wooden pencil might chew off the eraser from nervousness adding to the use of an eraser that is not attached to a pencil. In other cases, it could be that the person using the wooden or mechanical pencil might tap it excessively to the point of almost breaking it. Dropping either pencil on a frequent basis can result in permanent damage of the lead inside.Personally, I still own the same mechanical pencil I bought for drafting classes back in high school. That has been 30 years ago. I have been through nearly 100 wooden pencils since then for sketching.- Harold SinkAnswerThe Mechanical pencil would last longer because you can have multiple packages of refill lead but the regular pencil would eventually be sharpened to nothing but an eraser. AnswerA pencil because the mechanical you would run out of led and a pencil you would just sharpen Answerpencil (these answers are really based off of more opinion than fact.)AnswerCalabuka - The answer to this question is dependant to how it is used. You may snap the mechanical pencil and no longer will it work but the pencil (snapped) will. But you can sharpen the pencil all the way to nothing and a mechanical pencil uses refillable led you can buy at the store. This question really depends on how the pencil/mechanical pencil is used. AnswerMechanical pencils always break and the lead is too thin. Good old fashioned regular pencils are the best.zeldaloverit depends. if u wont the base with a lot of led, then macanical. if u wont a ton of sharpening, then a normal pencil
What do you do when your pencil runs out of lead?

Should I buy mechanical or wooden pencils?
Mechanical pencils can be used over and over again by simply replacing the lead, thus possibly saving money. The lead in a mechanical pencil, depending on the width, could be either more or less likely to break. When it comes down to it, it's really just a matter of preference.

Which pencil lead is thinner 05 or 07?
Owning both 05 and 07, 05 is thinner. It is more prone to breaking. I have resorted to purchasing only .07 mechanical pencils. And my wife recently brought me a box of mark sense lead, that is only about 2 inches long, but appears to be .144 lead - it does appear twice as thick as .07 - now if only I can find a pencil that uses it!
