I am wondering if you are referring to "heat index" and "wind chill factor". These terms refer to what the temperature actually is and what it feels like.
Hot air. That's what makes it float.
Heat flow determines how hot or cold something feels when you touch it.
Air can be either cold or hot.
Yes. There is such thing as hot air and cold air
Thermal conductivity most determines how hot or cold something feels when you touch it. The nerve endings in your skin determine what is hot and cold when you touch it.
Hot air rises and cold air falls.
Both. Since hot air is less dense than cold air, the hot air rises as the cold air falls (i.e. as the cold air displaces the hot air). If you were to dye hot air & then inject it into the center of a room, you would observe the dyed hot air rising. What you may not realize is that gravity draws the (invisible) surrounding dense cold air downwards as it displaces the (visible) less dense dyed hot air. === Previous Posters Answer: Hot air rises
what is the diffrence in hot and cold air particles
Cold air is compact air Hot air is less dense than cold air Ergo, hot air rises ; cold air sinks
technically hot air does not really rise it is the cold air that sinks below it because it is more dense.
Yes, cold air has a higher density than hot air, and that is why hot air balloons rise, it rises above the cold air. hot air is less dense than cold air^
