Worked example
Find the average kinetic energy when Temperature = 293 K.
Using Ek = 3/2kT: Average kinetic energy = 6.07 × 10⁻²¹ J.
Frequently asked questions
What is the formula for Average kinetic energy of a gas particle?
Ek = 3/2kT. k = Boltzmann constant. Temperature is a measure of average particle energy.
What do the letters stand for, and what units are used?
Average kinetic energy in J, Temperature in K.
How do you calculate average kinetic energy?
Put the values into Ek = 3/2kT. For example, with Temperature = 293 K, average kinetic energy = 6.07 × 10⁻²¹ J.
Can I solve for a different value?
Yes. In the calculator above, pick the circle next to any value (average kinetic energy, temperature) and fill in the others: it rearranges the formula for you.
