Thermal conductivity of solid metals with rise in temperature normally;

Thermal conductivity of solid metals with rise in temperature normally;
1). increases
2). decreases
3). remains constant
4). may increase or decrease depending on temperature

• Thermal conductivity depends on the chemical composition of the substance.
• Thermal conductivity of the liquids is more than the gasses and the metals have the highest.
• Thermal conductivity of the gases and liquids increases with the increase in temperature.
• Thermal conductivity of the metal decreases with the increase in temperature.
• Metal, crystalline in structure, have greater thermal conductivity than non-metal.
• Thermal conductivity is affected by the phase change.

2). decreases
