Inside of vacuums, there is no air. In these spaces, you can create an environment, where there is little/no air resistance.
Higher altitude air is less dense. Less density means less air; less air means less friction, and less friction means a higher speed.
Warm air is less dense (lighter) than cold air..that is why warm air rises and cold air settles
The air is less dense.
Yes, there is less oxygen in humid air compared to dry air.
The air inside a balloon is less dense than the air around it. When the balloon is inflated, it contains less air molecules compared to the same volume of air outside the balloon, making it less dense.
its has more pressure
Air becomes less dense as you climb a mountain. This is because at higher altitudes, there is less atmospheric pressure pushing down on the air molecules, causing them to spread out more, making the air less dense.
If a balloon is filled with a substance that's less dense than air ... such as helium, hydrogen, steam, or warmer air ... then the balloon is less dense than air.
No, less dense air typically results in lower air pressure. High air pressure is often associated with denser air, while low air pressure is associated with less dense air.
When dense,cold air meets less dense,warmer air, the warm air is pushed up
When dense,cold air meets less dense,warmer air, the warm air is pushed up
The air in Antarctica is less poluted because there arn't cities and cars and things that pollute the air.
