Which will rise up faster dry air or moist air?
dry air rises up faster because the dry air has less density n therefore it rises up faster than moist air
Why is air compressed when an object is traveling faster than the speed of sound?
The supersonic object is hitting air molecules faster than they can get out of the way, so they pile up.
Does compressed air go faster than helium?
Speed is not determined by the composition of a gas. Too may other variables. As phrased, there is no answer possible to your question. Will helium seep out of a balloon faster than air? Yes. Go faster? Explain your question.
Can Lightning and thunder occur simultaneously?
No. Thunder is the result of lightning when it hits the ground. After lightning hits the ground the air expands (because of the increase in temp.) and quickly condenses. That air condensing is what we hear when there is thunder. Because light travels faster than sound we see lightning then hear thunder.
Cooled air that is heavier than surrounding air will?
Sink towards the ground
What is the advantage and disadvantage of water transport?
We need to consider the three basic types of transport: ground, water, and air. Ground transport is the most convenient for places that are not extremely distant or separated by unbridged bodies of water. If ground transport is not feasible, the alternatives are water or air transport. Air transport is faster but more expensive. Water, especially for large, heavy shipments, is much more economical. In addition, some people enjoy the experience of an ocean voyage more than they enjoy flying.
Why can you hear the sound of the thunder faster if you place your ear against the ground?
Because the ground is denser than air. The noise of the thunder, form where the lightning bolt strikes the earth, travels faster in the ground than it does through the air.
When a sound from a source is refracted away from the surface of the earth it gives an indication that the air is cooler than the ground?
Ground is cooling faster than the air.
Why do sound waves move faster through the ground than through the air?
particles of matter are packed more loosely in the ground than in the air.
Are you faster in the air or on the ground while skiiing?
i think it is faster in air because in air there isn't any friction .....
What transport is there to get to Spain?
Sea, air, ground (incl. rail) ?
Are signatures required when receiving hazardous material by ground or air transport?
no
What is the difference between air transport and water transport?
Air transport is faster because it has less resistance and friction, whereas water transport is slower because the waves will crash against whatever you are using for transport and slow it down. However, it doesn't mean that air transport has completely no resistance; the air can still go against you and slow you down.
Why does sound travel faster closer to the ground than in the air?
The stiffer meduim- travels quicker The denser the medium-travels slower
What Is air mail shipping?
Goes by air vs ground and usually faster as a result.
What happens if the ground is cooler than the air?
When the ground is cooler than the air you get fog.
What the advantage of air transport?
transporting to the destination faster... More memorable time Fun!
