Answer:
Zero Kelvin
Explanation:
The average kinetic energy of the particles in a gas is related to the absolute temperature of the gas by (for an ideal monoatomic gas):
[tex]E_K = \frac{3}{2}kT[/tex]
where
k is the Boltzmann constant
T is the absolute temperature
The average kinetic energy is the energy possessed by the particles due to their motion; we see that this energy becomes zero when T = 0, which means when the substance reaches a temperature of zero Kelvin. Therefore, this means that at this temperature all the particles stop moving.
