# Find the average kinetic energy of gas molecules at t = 27 ° C.

July 24, 2021 | education

| The average kinetic energy of gas molecules can be calculated by the formula:

Ek = 3/2 kT, where k is the Boltzmann constant (k = 1.38 * 10-23 J / K), T is the absolute gas temperature (T = 27 ºС = 27 + 273 K = 300 K).

Let’s calculate the average kinetic energy of gas molecules:

Ek = 3/2 kT = 3/2 * 1.38 * 10-23 * 300 = 621 * 10-23 J.

Answer: The average kinetic energy of gas molecules is 621 * 10-23 J.
