Question

According to the kinetic theory of gases, the kinetic energy of molecules is proportional to which factor?
A. Concentration in moles/liters
B. temperature in kelvin

Answer 1

C. volume in liters
D. pressure in atmosphere

Answer 2

It is temperature in kelvin as temperature increases the motion of the atoms.

Answer 3

Hint:
using the equipartition theorem, the kinetic KE energy of a molecule as a pointlike particle is:
\[\Large KE = \frac{3}{2}KT\]
where K is the Boltzamnn's constant, and T is the absolute temperature

Answer 4

a pointlike particle, means that we neglect any internal degree of freedom of that particle
