Question

which of the following properties are intensive, and which are extensive? check the
malleability
○ intensive
○ extensive
length
○ intensive
○ extensive
done
hardness
○ intensive
○ extensive
volume
○ intensive
○ extensive
done

Explanation:

• Malleability: Intensive properties don't depend on the amount of substance. Malleability (ability to be hammered into sheets) is a characteristic of the material itself, not the amount, so it's intensive.
• Hardness: Hardness (resistance to indentation/scratching) is a property of the material, not dependent on the quantity of the substance, so it's intensive.
• Length: Extensive properties depend on the amount of substance. Length of an object depends on how much of the material is there (e.g., a longer wire has more material), so it's extensive.
• Volume: Volume is the amount of space a substance occupies, and it depends on the quantity of the substance (more substance means more volume), so it's extensive.

Answer:

• Malleability: $\boldsymbol{\text{intensive}}$
• Hardness: $\boldsymbol{\text{intensive}}$
• Length: $\boldsymbol{\text{extensive}}$
• Volume: $\boldsymbol{\text{extensive}}$
