3. Thermal conductivity of liquids

For many organic liquids, thermal conductivities are between 10 and 100 times greater than for gases at the same temperature. Thermal conductivity for most liquids, at temperatures below the boiling point, is between 0.10 and 0.17 W.m ^-1 .K ^-1 . The thermal conductivity of liquids decreases with increasing temperature. It is not very sensitive to pressure.

The thermal conductivities of liquids such as water, ammonia or highly polar liquids are much higher than those of normal liquids. Liquid metals also have very high thermal conductivities, around 100 times higher than those of organic liquids.
