Answer
Melting point
Explanation
Materials used in high-temperature applications must have a high melting point to maintain their integrity and performance.
Common mistake
Misinterpreting density as the sole factor for material selection
Students often think that a material’s density alone determines its suitability for a particular use, ignoring other properties such as strength, thermal conductivity or corrosion resistance.
Explain that while density is important, other properties like mechanical strength, hardness, thermal expansion, electrical conductivity and resistance to corrosion must also be considered when matching a material to a specific application. Use examples such as aluminium alloys being chosen for aircraft parts because of their low density combined with adequate strength, not just because they are light.
