A Nitrogen Molecule Has a Diameter of About 0

question 17

Multiple Choice

A nitrogen molecule has a diameter of about 0.29 nm. The mean free path of a nitrogen molecule in a tank of dry nitrogen at room temperature (293 K) and standard pressure (1 atm) is about 0.10 µm. A tank containing nitrogen at standard temperature (273 K) and pressure has volume V. If the tank is compressed by means of a piston to 20% of its original volume, what is the mean free path for a nitrogen molecule under the new conditions?

• A) 0.020 µm
• B) 0.125 µm
• C) 0.080 µm
• D) 0.112 µm
