What would happen to the average kinetic energy of the molecules of a gas sample if the temperature of the sample increased from 20°C to 40°C?
A)It would double.
B)It would increase.
C)It would decrease.
D)It would become half its value.
E)Two of these.

Question

Quizplus · Accepted Answer

The average kinetic energy of the molecules of a gas sample is directly proportional to the temperature of the sample in Kelvin. When the temperature is increased from 20°C (293.15 K) to 40°C (313.15 K), the average kinetic energy of the molecules will increase as well. Therefore, the answer is B) It would increase.
