A postulate of the kinetic molecular theory is listed.
Postulate: The average kinetic energy of gas molecules is related to the temperature
of the gas.
Which of the following activities can be used to demonstrate the postulate? (1 point)
1) Recording the change in pressure when heating an inflated tire
2) Observing the ease of pushing the plunger of a syringe containing gas
3) Observing colored gas spreading into an inverted jar placed on top of a jar
containing the gas
4) Detecting the smell of moth balls in an entire closet when the moth balls are
kept at the bottommost shelf of the closet

1) Recording the change in pressure when heating an inflated tire

Explanation:

This happens because with an increase in temperatures, the kinetic energy of the gas in the tire increases. The increase in kinetic energy means the molecules move more rapidly. There is an increased rate of collisions between the gas molecules, and increased energy of the collisions, and between the gas molecules and inner walls of the tire hence the increased pressure. Pressure and temperatures and directly proportional s long as the volume of the gas is kept constant.

the correct answer would be b) volume versus temperature, because they are also directly proportional.
