#1: when you heat an air-filled, sealed can, what happens inside? a. the collisions of air molecules against the wall of the can are weaker and less frequent. b. the collisions of air molecules against the wall of the can are stronger and more frequent. c. the collisions of air molecules against the wall of the can do not change. **my b is that correct @aaronq ?

According to the kinetic molecular theory of gases, the behavior of gas in a closed container is a function of the kinetic energy of the individual gas molecules, which exhibit perfectly elastic collisions with each other and the container walls. As such, when heat energy is added to the can, the gas absorbs this energy, increasing the kinetic energy (and this the velocity, as kinetic energy is 1/2mv^2) of the particles. Therefore, the resulting behavior, due to the increased energy, velocity, and momentum, is that B. The collisions of air molecules against the wall of the can are stronger and more frequent.
