Decreases is correct.

Here already mention the rise in temp so thermal conductivity of liquid decrease with increase in temp.

Because after 100f it behaves as gas and increase in temperature then the thermal conductivity increases so the answer is D.

You are right @Avinash because due to hydrogen bonding it increases up to 113 C and then decreases with rise in temp.

Manish said:   1 decade ago
As we know thermal conductivity of liquid decreases with increase in temperature so option B is correct.

Aluminium is also this kind of metal in which temperature increase then conductivity decrease.

Water is exception about the theory that k of liquid decreases with rise in temperature?

DEEPAK CHOUDHARY said:   1 decade ago
Fusion curve of water has negative slope so that water is expands on freezing like that.

Hitesh Daka said:   9 years ago
Here, the thermal conductivity of water increases with increase in temperature.

MAYUR said:   5 years ago
Thermal conductivity increase with increase in temperature only for water.

Friends, please note that density of water is max at 4-degree centigrade.
