Question

Does thermal conductivity change with pressure?

Answer 1

Explanation:

For all liquids the coefficient of thermal conductivity increases with increasing pressure. Upon compression molecules draw together, their mutual attraction grows, therefore, viscosity and thermal conductivity increase

Answer 2

Answer:

Pressure doesn't have any significant affect on its thermal or electrical conductivity since they are almost incompressible. Gases: Due to increase in pressure, number of collisions increases and hence energy dissipation due to such inelastic collisions leads to decrease in thermal conductivity of gases.

Explanation:

The thermal conductivity of the gas is directly proportional to square root of temperature and inversely proportional to square root of the molar mass. Thermal conductivity of the gas is independent of pressure in a wide range of pressure.
