The average kinetic energy of the particles is directly proportional to the
C) Kelvin temperature
Explanation:
The average kinetic energy of the particles in a substance is given by the equation:
[tex]KE=\frac{3}{2}kT[/tex]
where
KE is the average kinetic energy
[tex]k=1.38\cdot 10^{-23} J/k[/tex] is a constant, called Boltzmann constant
T is the absolute temperature of the substance, in Kelvin
From the equation, we see that the average kinetic energy of the particles is directly proportional to the
C) Kelvin temperature
This is because the Kelvin temperature gives a measure of the amount of motion of the particles in a medium: indeed, at absolute zero (= temperature of zero Kelvin), the particles in a substance have ideally no kinetic energy, and therefore T = 0).
