QUESTION:
Problem 64P
Make a rough estimate of the thermal conductivity of helium at room temperature. Discuss your result, explaining why it differs from the value for air.
ANSWER:
Step 1 of 5
The thermal conductivity of gas is given by
Also, we know that,
Hence the thermal conductivity becomes
Now using this equation we have to estimate the thermal conductivity of helium at room temperature. Then we have to discuss why the thermal conductivity of helium differs from the thermal conductivity of the air at the same temperature.
