Effect of Pressure on Thermal Conductivity of an Ideal Gas
Pressure has a significant impact on the thermal conductivity of an ideal gas.
Explanation:
Basic Concept:
- Thermal conductivity is a measure of a material's ability to conduct heat.
- In the case of an ideal gas, the thermal conductivity is primarily dependent on the mean free path of the gas molecules and their collision frequency.
Effect of Pressure:
- As pressure increases, the density of the gas increases as well.
- With higher density, the mean free path of the gas molecules decreases.
- Decrease in mean free path leads to an increase in the number of collisions between gas molecules.
- More collisions result in more efficient heat transfer within the gas.
Result:
- Due to the increased number of collisions at higher pressures, the thermal conductivity of an ideal gas remains constant.
Therefore, in the given scenario, the correct answer is that the thermal conductivity of an ideal gas remains constant with an increase in pressure.
