Question

The thermal conductivity of solid metals increases with a rise in temperature. Comment

Answer 1

• Thermal conductivity refers to the ability of a given material to conduct or transfer heat. It is generally denoted by the symbol ‘k’.
• Some factors known to influence the thermal conductivity of metals are:-

1. Chemical composition
2. Atomic structure
3. Phase changes
4. Grain size
5. Temperature and pressure

When the temperature of the solid metal increases, the thermal conductivity of the solid metal also increases as the thermal conductivity of the metal is directly proportional to the molecules' absolute temperature and mean free path.
