Temperature is the average kinetic energy of a set of molecules. Think about that: From physics, you know that the kinetic energy of an object is proportionate to its mass, and the square of its velocity. By adding heat to a system, you are adding energy. That energy is manifested as temperature.
What else can I help you with?
What happens to particles when their temp is increased according to kinetic theory?
The water molecules increase their speed
Why doesnt earth's atmosphere leaks out?
Gravity holds it in place. It is possible that now and then individual molecules acquire enough speed to escape, but the effect is negligible.Gravity holds it in place.

What factor most likely has the greatest effect on the number of molecules mitochondria can produce?
The Speed of the H+ ions
Which factor most likey has the greatest effect on the number molecules mitochondria can produce?
The speed of the H+ ions.
How fast are molecules in the air moving?
Molecules in the air move at speeds that vary due to factors like temperature and pressure. On average, at room temperature, most molecules in the air move at speeds ranging from 300-500 meters per second.
Does mean molecular speed change as much as the temperature water heats up?
Yes, as the temperature of water increases, the mean molecular speed also increases because the molecules gain kinetic energy. This increased kinetic energy causes the water molecules to move faster and collide with each other more frequently.
What is the effect of medium on the speed of sound?
Sound travels faster through denser media because their molecules are closer together.

Which occurs when air is compressed A. Air Temp rises and air molecules move faster B. Air temp decreases C. Air temp decreases and air molecules move faster D. Air molecules move slower?
A. air temperature rises and air molecules move faster
When high speed molecules mix and collide with slower speed molecules the high speed molecules do what?
Slow down and the temperature drops.
What effect does density have on air temp?
no
Does air temp effect light?
yes
