# Kinetic energy and speed of Hydrogen and Oxygen molecules

Not what you're looking for?

Hydrogen and Oxygen molecules in a gas sample have the same temperature. This means that the hydrogen molecules, on the average have the same kinetic energy and speed as oxygen molecule?

##### Solution Summary

The solution discusses the Kinetic energy and speed of Hydrogen and Oxygen molecules which have the same temperature.

^ denotes power
E denotes 10 raised to the power

Kinetic energy of a molecule = 3/2 kT
where
k= Boltzmann's constant=1.38x 10^-23 J/K= 1.38E-23 J/K
T=Temperature in Kelvin

Thus if temperature is the same it means that kinetic energy of the molecules are equal as there are no other factors apart from k and T

Kinetic energy of a molecule = 1/2 m v ^2
Equating the two
3/2 ...
