WebAnswer: A material's hardness refers to its ability to resist having its molecules being rearranged into another form. Think of a solid chunk of steel. It is very hard but not very brittle. Brittleness refers to how a material responds to stress being applied to it. Materials under force undergo...
WebFeb 5, 2024 · Since hardness is the opposite of brittleness, there are many differences between these two terms. The main difference between hardness and brittleness is that hardness is resistance to scratching or deformation, while brittleness is the tendency to crumble. Key areas covered. 1.
