Answer:
The temperature of a substance in chemistry, is taken as a measure or estimate of the average kinetic energy ([tex]K_{avg}[/tex]) of the atoms or molecules contained in the substance. The 6.02 × 10²³ particles (atoms or molecules) within 1.0 mole of each substance can each posses different amount of kinetic energy at any given time. Some particles move very fast while others move very slow such that the kinetic energy of all the particles are only representable by a distribution and a conclusion regarding the different aspects of the kinetic energy distribution of the particles of the substances is not easily possible
Explanation:
For a gas, we have;
[tex]KE_{avg} = \dfrac{3}{2} \cdot k \cdot T[/tex]
Where;
[tex]KE_{avg}[/tex] = The average kinetic energy
k = 1.38 × 10⁻²³ J/K
T = The gas temperature in Kelvin
