Answer to Question #136299 in General Chemistry for Ashure

Question

Hi I want to ask a question on how to get the average kinetic energy when molecular weight is given and temperature

Answer 1

Kinetic energy refers to the energy which particles contact while in motion.

Kinetic energy is obtained by$k.E = 1/2(mu^2)$

Where m is the mass in our case molecular mass ,and U² is the molecular speed of the atom.

U takes form in three dimension x,y,z as motion of particle is random.

U =u_x +u_y+u_z.

_{hence the molecular speed (u) includes all the coordinates.}
