Enter the temperature of an ideal gas into the calculator to determine the average kinetic energy of the particles in the gas.

## Average Kinetic Energy Formula

The following formula is used to calculate the average kinetic energy of a gas.

K = (3/2) * (R / N) * T
• Where K is the average kinetic energy (Joules)
• R is the gas constant (8.314 J/mol * K)
• N is Avogadro’s number (6.022 * 1023 atoms/mol)
• T is the temperature in Kelvin

To calculate the average kinetic energy of a gas, divide the gas constant by Avogadro’s number, multiply by the temperature, then again by (3/2).

## Average Kinetic Energy Definition

Average kinetic energy is defined as the average energy contained within the movement of particles of a gas.

## Average Kinetic Energy Example

How to calculate average kinetic energy?

1. First, determine the temperature of the gas.

Determine the temperature of the gas and depending on the units, convert them to units of Kelvin.

2. Calculate the average kinetic energy.

Plug in the value of the temperature in Kelvin into the formula to determine the average kinetic energy.

## FAQ

What is the average kinetic energy of a gas?

The average kinetic energy of a gas can be calculated using the formula (3/2)*(R/N)*T for ideal gases only.
