Thermal conductivity of water in general with rise in temperature

A Increases
B Decreases
C Remain constant
D May increase or decrease depending on temperature

Correct Answer: May increase or decrease depending on temperature

Apart from liquid metals, water has the highest thermal conductivity of any liquid. For most liquids, the thermal conductivity (the rate at which energy is transferred down a temperature gradient) falls with increasing temperature but this occurs only above about 130°C in liquid water
