once again in English?
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
if you mean how the hot air in a hot air balloon makes it rise, its because hot air is less dense than cold air. when cold and hot air meet the cold air sinks thus making hot air left to rise.so when you put hot air in a balloon the air would rise. hope this helps.
Air can be either cold or hot.
Yes. There is such thing as hot air and cold air
what is the diffrence in hot and cold air particles
Since hot air is less dense than cold air, when hot and cold air collide, the hot air is forced to rise over the colder air.
The temperature and density of the air masses. the air masses moves when hot air and cold air gets together

Air can be either cold or hot.
One of the reasons a 2000 Jeep Cherokee heater would randomly blow cold air and then hot air and then cold might be that there is a problem with the hot/cold duct. The air or a vent might be inadvertently blowing periodically.
When cold air and hot air mix together it forms a tornado.
well, blow dryers are a good type of way to dry your hair and it blows HOT air but if you use cold air its still okay. but to cold would make your hair freeze so i would probably say hot air
Yes. There is such thing as hot air and cold air
i dont know its used as hot and cold put together and fly
The temperature and density of the air Masses.the air masses move when cold air and hot air gets together.
