Question

The velocity of the nitrogen molecule in room temperature air is:

• A. zero
• B. 10 m/s
• C. 100 m/s
• D. 500 m/s
• E. 5000 m/s
  \bigskip

Hint:

The velocity of molecules in gases can be estimated using the ideal gas law and kinetic theory. Typical molecular speeds are often in the range of hundreds of meters per second.

Answer 1

The Correct Option is D

At room temperature, the velocity of nitrogen molecules in air is typically around 500 m/s. This is the average velocity of the molecules according to kinetic theory.
