very hard
it dries out
To prevent a pencil led from fading is to not bare down so hard on the paper.
That would depend if the pencil were an H or a B. Artist pencils are identified with a number and a letter. H is for hard. A 6H pencil would be harder than a 4H pencil. B is for soft. A 6B pencil would be softer than a 4B pencil.
The literal definition is clay and chemicals fired together to create a hard brittle heat resistant material
The lithosphere, which consists of the crust and uppermost mantle, is considered hard and brittle, unlike the asthenosphere, where rock is considered ductile.
brittle
Yes it will. It will become more brittle and actually break easier than a pencil which is not frozen.

hard and brittle so YES
Ionic solids are brittle and hard as they are bonded with electrostatic bonds.
brittle meaning EASILY BREAKABLE so i don't think it is brittle...
They get hard and brittle when they dry out.
Hardness is the question of how difficult it is to make an impression on a substance. Brittleness is the question of how easy it is to break. Granite is a stone which is very hard but not brittle--it is hard to carve and also hard to break. A plank of wood is not as hard as stone but is not very brittle. You can carve on it with a knife but it won't shatter if you drop it. Glass is hard and brittle. Chalk is not hard but it is brittle.
The pencil wrote as hard as a wall
To be brittle is to be hard and breakable. An example sentence would be: The older she got, the more brittle her bones seemed to be.
Pencil lead is a brittle solid and it is graphite made in different hardness's. The thickness and shape of the actual rod of graphite can vary greatly
