Question

The average kinetic energy of hydrogen molecules at $300K$ is $E$. At the same temperature, the average kinetic energy of oxygen molecules will be

• A. $E/16$
• B. $4E$
• C. $E/4$
• D. $E$

Answer 1

The correct option is D $E$

As we know, average kinetic energy,
$E=\frac{3}{2}KT$
$\because E\propto T$
Since the temperature is same, so average kinetic energy of hydrogen molecule and oxygen molecule will be same.
