At constant temperature, the thermal conductivities of gases __________ with rise in pressure.

Question

Quizplus · Accepted Answer

At constant temperature, the thermal conductivities of gases decrease with a rise in pressure. This is because, as pressure increases, the density of the gas increases, leading to a decrease in the mean free path of the gas molecules. This results in less efficient energy transfer between molecules, thereby reducing the thermal conductivity.
