yes, as the particles of air are heated, it moves more rapidly, which causes it to expand

Cold air has more molecules occupying a cubic centimeter of space then warm air therefore it has a what pressure?
Cold air has more molecules occupying space than warm air, therefore it has high pressure.
Does cold air or warm air have more molecules occupying a cubic centimeter of space?
cold air
Why doesn't cold air takes up space?
Cold air does take up space. All matter does.Cold air just takes up less space than warm air.
The molecular activity associated with heat causes warm air to blank than colder air?
heat causes warm air to occupy more space than colder air.
Why does thermal energy flow upwards?
I assume ... Thermal meaning warm(th) and by upwards flow you would be talking about air? Immagine this ... If you take a bit of metal and you warm it up (a lot), it expands. something very similar happens to the air. When you warm things up what you are really doing is making the particles move around a whole bunch more ... meaning that they need more space. Now if the particales are suddenly taking up more space and so are further apart from each other you will have fewer particles in a 10 by 10 space full of warm air than in a 10 by 10 space of cold air. This means that the 10 by 10 space of warm air is also lighter than the 10 by 10 space of cold air and so can rise to the top, creating an 'upward' flow. If we didnot live on a planet and so did not have such a strong gravitational field, this wouldn't happen! (not to mention that there is no proper 'up and down' in space)
Cold air has more molecules occupying a cubic centimeter of space than warm air therefore it has what kind of pressure?
higher
Are cold air masses denser than warm air masses?
Yes, cold air masses are denser than warm air masses. The reason for this is because heat excites atoms so they take up more volume in space. Meaning they take up more volume of heat which leaves little warmth left and a lot of cold left. The warmth is thinner and vice versa, the cold is denser.
Does convection take place because cold air is more dense than warm air?
yes
What is cold air more than warm air?
Cold air is more dense than warm air.
Which holds more water vapor warm air mass or cold air mass?
The warm air mass
Are molecules more active in warm air or cold air?
molecules are more active in warm air. Hope this helped
What air holds more moisture?
Warmer temperatures hold more water.
