Yes, one example is a tornado
No, air on its own cannot hold a person up. The lift required to overcome gravity and support a person's weight typically comes from other sources such as buoyancy (in the case of balloons or aircraft) or lift generated by wings (in the case of airplanes).
Pressurized air doesn't provide enough force to launch a water bottle rocket effectively. Using water and air creates a more powerful thrust because the water rapidly expands into steam when the air pressure is released, generating a higher force for propulsion.
A liter bottle can hold approximately 1 liter of air.
When warm air rises and expands, it cools down. As it cools, its capacity to hold water vapor decreases, leading to condensation and the formation of clouds. This process is known as adiabatic cooling.
First of all, the atmosphere is the air. Secondly, air is matter, all matter is affected by gravity. Imagine this: the sea is liquid, it lies on the earth, pulled by gravity. the atmosphere is also like this except it is a "sea" of air, it lies on the earth, pulled by gravity.
Yes, if you have enough helium in a balloon that is large enough and strong enough to stand the strains involved.
that depends on who the person is. I can hold my breath for about 12-15 seconds. I saw a person on TV who could hold their breath for about 5 minutes.
old enough to hold it up.
Canopy beds lend an air of elegance and grandeur to a bedroom. The strength of the frame of a canopy bed can very depending on the construction material and the quality of the craftsmanship. A canopy bed should be strong enough to hold heavy drapes that may be used for the canopy.

At Loch Ness, click the left side of the truck, then click and hold the valve stem (arrow) until enough air escapes.
None, air in the heart will cause an embolism stopping blood flow.
If you are asking how a tornado holds a house, the answer is fairly simple. The winds in a tornado travel upwards rapidly in addition to spinning. In the very strongest of tornadoes this wind is strong enough to remove a house from its foundation and lift it into the air.
Tornadoes need strong thunderstorms in order to form. Thunderstorms, especially strong ones require warm moist air to power them. Cold air simply does not have enough energy.
Yes, but it is tough to do. A Bear Hug prevents the person from inhaling, or from inhaling deeply. If you can squeeze tight enough then you can force the person to pass out from lack of air. However, once you let go the person will start breathing again. A Bear Hug would only be fatal if you were strong enough to seriously restrict their breathing and then only if you held it on for quite a while after they passed out.
Hold the valve stem until enough air has gotten out of the tire.
It's light and thin and since it's flat the air current catches it and causes it to float. The reason it floats is because it's flat and wide, spreading out, and the air is able to hold it up. Now if you were to crumple it into a ball and drop it it would fall to the ground because there's not enough space and room to hold it. It's to heavy now and there is not enough room for the air current to hold it. That's why on a paper airplane it has flast wings; so that the air current can touch taht and keep it a float.
