Question

Which formula gives the average kinetic energy per molecule of an ideal gas?

Options

• E_k = \[\frac {1}{2}\] mv²

• E_k = 3k_BT

• E_k = \[\frac {3}{2}\] nRT

• E_k = \[\frac {3}{2}\] k_BT

Answer 1

E_k = \[\frac {3}{2}\] k_BT

Explanation:

Average kinetic energy is directly proportional to absolute temperature.
