Answer 2

Hard Materials example: Iron, steel, wood, stone, brick, glass, bone, teeth, diamond.

Soft Materials example: Sponge, cotton, wool, foam, rubber, candle wax, butter, chalk, clay, feathers, flour, skin etc.

Hard materials:

• Hard materials are those that are difficult to crush, chop, distort, or scrape.
• Two examples are iron and glass.
• The term "soft material" refers to substances that are easily crushed, sliced, bent, or scraped.
• A few examples are the tissue that makes up the majority of the animal kingdom, colloids, polymers, liquid crystals, gels, emulsions, foams, and others.
• The regular and frequently "tight" crystalline structure of a substance determines how hard it is.
• For materials like glass, diamonds, and other hard ones, this is unquestionably true.
• Steel is hardened by heating it to a high temperature, followed by quenching.

Soft materials:

• Soft materials can "give" when a force is applied because they have a structure that is more flexible in the linkages between molecules or in the crystal structure.
• Many weaker materials stay robust because the substance contains numerous connections.
• For instance, the rubber in a tire is quite soft yet quite robust, and it conforms to the road's thin surface structure.
• This is true because rubber molecules are coupled to one another to form lengthy strings.
