A)1.15
B)1.33

D)1.78
E)2.47

Question

Quizplus · Accepted Answer

The average kinetic energy of an ideal gas is directly proportional to its absolute temperature (in Kelvin). Therefore, when the temperature increases from 300 K to 400 K, the factor by which the average kinetic energy increases is 400/300 = 1.33.
