It's softer. #1 softest, #2 slightly harder, #3 harder than #2, etc.
Softer.
a #1 pencil is softer than a#2 pencil
Numbers and letters on the sides of some pencils (Art & Drafting pencils) is used to signify the type of lead that it contains, or more specifically the hardness of that lead. The higher the number/letter combination, the harder the lead. Conversely, the lower the number/letter combination, the softer the lead. The typical pencil (#2 pencil) contains HB Grade lead. PencilPages.com notes (from The Pencil Hardness Test); "The hardest is a 9H, followed by 8H, 7H, 6H, 5H, 4H, 3H, 2H, and H. F is the middle of the hardness scale; then comes HB, B, 2B, 3B, 4B, 5B, 6B, 7B, 8B, and 9B, which is the softest. Another grading method uses numbers; the equivalents would be #1=B, #2=HB, #2-1/2=F, #3=H, and #4=2H." The H represents hardness and the B represents blackness.
A pencil is 0.25 inches or as thick as a 2 gauge wire.
depends on the hardness and how its used - i have a HB with a thin hard lead that i have been using for laying out drawings that has been in use about 2 years now - and then i use solid 3/8 inch thick graphite 9B pencils that go in about a week I just tested it with my 6th grade class. We drew a line for 1/8 of a mile and it used 1/8 of the pencil lead. This reasoning means that we would use 1 inch of a pencil for 1 mile. Thus, the average 7inch pencil can draw 7 miles of a line. This does not take into account any variables such as the thickness of the lead, the pressure of the writer on the pencil, and the imperfect line that was drawn. However, I think it is safe to say that the 35 miles myth seems a bit far-stretched.
Fluorite with a Mohs hardness of 4 would be scratched by quartz (with a hardness of 7). Both calcite (Mohs hardness 3) and talc (Mohs hardness 1) are softer than fluorite.
i like to use a good lead pencil number 1 because the lead isn't as hard as a number 2 pencil and therefore is easier to shade with. Good luck with your drawing!
Because it can't print fast enough to beat number 1. The #2 pencils are so labeled because their darkness and hardness approximates those of a US classification (previously French and British) of graphite pencil leads. They are hard enough to resist breakage and soft enough to make a clear mark. Generally the harder a pencil is, the sharper the point can be, and hard pencils usually make dim marks. You can buy #1 pencils (softer and darker) and #3 pencils (harder and not as dark), and even #2.5 which indicates you are getting a slightly harder, less distinct graphite. Colored pencils tend to be softer and drawing pencils tend to be harder. (see the related link for more)
Yes, unless it is an extremely long pencil!
1 meter is about 3 feet so 36 inches about and a pencil isn't usually more than like 5.
Your pen-, I mean... a pencil! Yeah, a pencil is less than one meter long and wide.
It depends on which pencil you're talking about. Most pencils are made less than 1 meter long.
Yes, of course!
A yard
the softer mineral can be scratched by a harder mineral. Ex: talc is 1 and quartz is 7 so quartz can scratch talc
3.95 NO Since an ordinary wooden pencil will float in water, clearly its density is less than 1.
It is the Mohs scale of mineral hardness. It characterizes the scratch resistance of various minerals through the ability of a harder material to scratch a softer material. The scale assigns numbers 1-10. 10 being the hardest of minerals(e.g. diamonds), and 1 being the softest minerals(e.g. talc). Generally minerals with a H<5 are softer minerals and minerals H>5 are harder.
