Cold air is compact air
Hot air is less dense than cold air
Ergo, hot air rises ; cold air sinks
No, cold sinks and heat rises.
Neither, heat is a form of energy and as such is contained within matter or exists as radiation. Heat energy and hot matter are very different things. In a fluid, hot matter will rise because it expands and hence decreases in density.
We feel cold when a drop of petrol falls on our skin because, heat from our body is transferred to petrol which usually evaporates at normal room temperature when it is exposed.
When cold air sinks to the ground The sun heat it again when the air gets hotter it will rise. The movement of this air is what we feel as wind.
Heat speeds up molecules, this causes the particles to rise
No, cold sinks and heat rises.
it is the middle so it is cold and hot
it is the middle so it is cold and hot by:michael bruce
Cold air does not rise, your question makes no sense.
After an occluded front passes temperatures drop if it was a cold front, and rise if it was a warm front. Pressure rises, and there is light-to-moderate precipitation, followed by clearing. Visibility improves and there is a slight drop in the dew-point if it is a cold-occluded front and a slight rise if a warm-occluded front.

There is no such thing as cold radiation. Cold is nothing in itself; it is merely the absence of heat - or just less heat. Heat, like light, radiates, but cold, like darkness, does not.What you may think of is cold convection; i.e., the fact that cold air will sink and warm air will rise. This effect is often confused as being 'cold radiation'.
Yes. Hot air is less dense, and therefore lighter than cold air, so it will rise as cold air will drop. A perfect example of this, is smoking rising to the ceiling in a fire, or smoke rising out of your chimney.
The cold in winter causes the humidity to drop by condensing it out. The heat in summer can cause the humidity to rise by evaporating more water from nearby bodies of water.
