Made from different materials. Bakelite is hard and rather brittle, polythene is softer and flexible.
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...

Bakelite is a thermosetting plastic. Its structure is made up of extensively cross-linked chains, which stop the chains from unfolding.

Stong, flexible, and soft are the best descriptor of bones.
Bones are strong, durable and slightly flexible. They can give a little. they are white and brittle when they dry out and are exposed to the air for some time.
brittle
hard and brittle so YES
hard and brittle so YES
They are hard and can not be melted on heating they become decomposed as Bakelite.

hard
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.
