Thermal conductivities of most of the liquids __________ with rise in temperature.
A)Increases
B)Decreases
C)Remains unchanged
D)May increase or decrease; depends on the liquid

Question

Quizplus · Accepted Answer

Thermal conductivities of most liquids decrease with a rise in temperature because, as temperature increases, the fluidity of the liquid increases, leading to a decrease in the frequency of molecular interactions that facilitate heat transfer.
