A jar has a mixture of hydrogen and oxygen gas in the ratio of 1 : 5. The ratio of mean kinetic energies of hydrogen and oxygen molecules is

Options

A. `1:16`
B. `1:4`
C. `1:5`
D. `1:1`

Explanation

To find the ratio of the mean kinetic energies of hydrogen and oxygen molecules in a jar where they are mixed in the ratio of 1:5, we can follow these steps:

### Step 1: Understand the formula for mean kinetic energy
The mean kinetic energy (KE) of a gas molecule is given by the formula:
\[ KE = \frac{3}{2} k T \]
where \( k \) is the Boltzmann constant and \( T \) is the absolute temperature.
