i dont know much about density of air but i do know this, if hot air is in a Basketball in the cold, it should be easier to score as the ball would physically rise if the air is too hot, but pressure would pop the ball first, so that stops it floating away, but yeah, hot air in a ball, on a cold day means the ball will bounce higher, and be easier to shoot, as less power is needed for the same shot, as on a hot day
Air moves from hot to cold.
If there is warm air in the balloon, cooler air makes the balloon rise and if there is cold air in the balloon warmer air makes the balloon fall.
Yes, in hot air the air is a lot thinner so there is less resistance compared to cold air which is a lot denser so more resistance.
Hot
Winds blowing is the effect of change in the temperature in the air. Since hot air is lighter than cold air, hot air develops from cold air nearer above ground, and when it's hot enough, it becomes lighter and rises up. Cold air stays nearer to the ground and the force of hot air coming up and cold air staying put forms winds. If the winds are big that means the change of temperature is big too.
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.
No, hot air is less dense than cold air.
Yes, air flows from hot to cold.
High winds, thunderstorms, or very cold air would have a detrimental effect on any hot air balloon flight.
hot is hot cool air is cold
when turning on air conditionor for cold air only get hot
