Conduction: Conduction in Liquids and Gases

Liquids and Gases are poor conductors of heat.

In liquids and gases, the atoms are spaced further apart as compared to solids, which will cause the collisions between the atoms to be lesser.

Liquids conduct thermal energy slower than solid, but faster than gases, as the atoms are spaced further apart when compared to solid but closer to each other when compared to liquid.

In liquids, it is the impurities (e.g. salt, dirt) that are conducting heat, not the water itself.
Thus, distilled water DO NOT conduct heat.

Gases conduct thermal energy the slowest among the 3 states as the atoms in gases is spaced furthest apart.

Gases are usually insulators of heat (poor conductors of heat).
e.g. Wool used as winter clothings.
It can trap pockets of air in it, reducing heat transfer by conduction.
