The ideal gas temperature dropped from 567 degrees to 147 degrees. How has the kinetic energy of the gasan molecules changed?

To find the change in the kinetic energy of the molecules of the ideal gas under consideration, we use the ratio: k = Ekn / Ekk = (3/2 * k * Tn) / (3/2 * k * Tk) = Tn / Tk.
Values of variables: Tn – absolute initial temperature (Tn = 840 K (567 ºС)); Tк – absolute final temperature (Тк = 420 К (147 ºС)).
Calculation: k = Tn / Tk = 840/420 = 2 p.
Answer: The kinetic energy of the movement of molecules has changed (decreased) by 2 times.
