One of the most important microscopic properties of gas molecules is velocity. there are several different ways to describe statistically the average velocity of a molecule in a gas. the most obvious measure is the average velocity v⃗ avg. however, since the molecules in a gas are moving in random directions, the average velocity is approximately zero. another measure of velocity is (v2)avg, the average squared velocity. since the square of velocity is always

pretty sure it's false

the ima (higher than 1m) will be greater than the ima with the height of 1m.

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.
