Answer: The correct statements about thermal conductivity are:
- The thermal conductivity of metals is generally higher than that of liquids.
- The thermal conductivity of solids is generally higher than that of liquids.
Explanation:
The rate at which transfer of heat takes place from one object to another by conduction over a unit cross section area of a material is called thermal conductivity.
Hence, more is the distance between atoms of a substance less will be its thermal conductivity. This is because more is the space between molecules of a substance more will be their random motion due to which there will be less effective energy transport.
The thermal conductivity of metals is very high than liquids.
Also, the thermal conductivity of solids is generally higher than that of liquids.
As gases have more space between its molecules so they have less thermal conductivity.
Thus, we can conclude that the correct statements about thermal conductivity are:
- The thermal conductivity of metals is generally higher than that of liquids.
- The thermal conductivity of solids is generally higher than that of liquids.
