Explain using KMT why the pressure of tires decrease in the winter.
At a low temperature the molecules have less kinetic energy which causes the particles to move less which causes there to be less wall collisions and therefore a decrease in pressure.

Explain using kinetic molecular theory why smoke is more visible out of a chimney in the winter than in the summer
What is smoke hangs out in the air longer because of the colder weather, which causes the particles to have lower kinetic energy and thus move slower.
