C) The dots would be close together to start with, and get farther apart as the plane accelerated.
A particle model
Brownian motion
The definition of particle motion is how much you're able to sleep on a daily basis.
motion
when it moves
solid, liquid, gas, plasma
Particle motion increases as energy (like heat) is added. The motion slows as energy leaves. Temperature is a measure of this change in particle motion.
due to large air space between particle
Your body will be in motion relative to what you are looking at outside the airplane.
Particle motion increases as energy (like heat) is added. The motion slows as energy leaves. Temperature is a measure of this change in particle motion.
Particle motion and thermal heat energy should both be increasing
The energy of the motion is decreased.
