Answer:
Average kinetic energy of 1 mole of a gas at 0 K is around 2780 J
Step-by-step explanation:
Kinetic energy is the energy of motion. Based on the kinetic theory of gases, the average kinetic energy (KE) is directly proportional to the temperature (T) of the gas particles.

where R = gas constant
T = temperature in Kelvin
Therefore, at T = 0 C i.e. (0 + 273)K = 273 K

The average kinetic energy is 2779.8 J
