Exam #2

Question 1

kinetic molecular theory of gases

Answer 1

• The gas particles are assumed to occupy negligible volume.

•The gas particles are in constant, rapid, random motion.

•The average kinetic energy of the gas particles is directly proportional to the absolute temperature.

Question 2

Answer 2

•some oxygen molecules are moving slower than some nitrogen molecules

•the nitrogen and oxygen molecules have the same average kinetic energy.

•some nitrogen molecules are moving slower than some oxygen molecules.
