Yes. There is such thing as hot air and cold air
Air moves from hot to cold.
Air can vary in temperature, so it can be cold or hot depending on the environment. Cold air is denser and can feel refreshing, while hot air is lighter and can feel warmer on the skin.
No, hot air is less dense than cold air.
Yes, air flows from hot to cold.
Yes, there is a difference in weight between hot air and cold air. Hot air is lighter than cold air because the molecules in hot air are more energetic and spread out, decreasing the overall density of the air. This difference in weight is a factor in phenomena such as convection currents.
Air moves from hot to cold.
Hot air rises and cold air falls.
Air can vary in temperature, so it can be cold or hot depending on the environment. Cold air is denser and can feel refreshing, while hot air is lighter and can feel warmer on the skin.
Warm air is lighter than cold air because cold air is denser, by dense I mean the particles in cold air are more packed together than it is in warm air. Therefore cold air is heavier which is why warm/hot air always floats above cold air (same thing with hot/warm and cold water). That is why warm/hot air is lighter than cold air.That's the reason why a hot air balloon only goes up when there's something producing hot air (like fire for example), and the only reason it goes back down is if you put out the fire. Remember this only happens because Hot water/air is less dense than cold air which makes it lighter.
No, hot air is less dense than cold air.
Yes, air flows from hot to cold.
hot is hot cool air is cold
No Gas Just hot air which is why it is called a hot air balloon. If you were wondering hot air is lighter than cold air which makes it rise so when it is trapped inside the balloon the whole thing will rise.
the hot air ballon is a thing
when turning on air conditionor for cold air only get hot
Hot air rises, so is lighter than cold air.
TEMPERATURE Cold air is denser
