?
Thermal conductivity of water _________ with rise in temperature.
Answer & Solution
Correct Answer:
Option
C
Thermal conductivity is a measure of a material’s ability to conduct heat.
In the case of liquids like water, thermal conductivity depends on the molecular motion and interactions between the molecules.
As temperature rises, the molecules in water gain kinetic energy and move more rapidly.
This enhanced molecular activity leads to better energy transfer between molecules, resulting in an increase in thermal conductivity over most of the liquid temperature range.
For water, thermal conductivity generally increases with temperature up to the boiling point.
Therefore, the correct answer is: Increases (Option C).

LoginSince in question already condition of temperature is mentioned (Rise - Increased)
Water - temperature directly proportional to "K"
Here K = Thermal conductivity of water
