Question
Air consists of many different molecules, for example, $\mathrm{N}_{2}, \mathrm{O}_{2}, \mathrm{H}_{2} \mathrm{O},$ and $\mathrm{CO}_{2} .$ Which molecules are the fastest on average? The slowest on average? Explain.
Step 1
This is given by the equation: \[ KE = \frac{1}{2} m v^{2} \] where \( KE \) is the kinetic energy, \( m \) is the mass of the molecule, and \( v \) is the velocity (or speed) of the molecule. Show more…
