by pointing and saying "there is air inside this thing"
Air should show indications of its presence through the pressure it maintains on the inside of the organism, and its ease in contrasting to water allows one to hook up a vacuum pump to the orifices of an organism, begin sucking only the air out, and due to the decrease of the internal air pressure, a mechanical change will come over the structure of the organism, thus indicating that air had been removed from the organism.
inside the nose, tiny hairs clean the air by catching dirt and other particles. the air also warms as it travels through the nose.
its many things. two of which are an empty sack of potatoes, and an organ inside a fish(aka air bladder)
Take a large container, pump out all the air from inside it. Weigh it. Put air inside and then weigh it again. The difference would be the weight of the air inside. Air molecules have mass (air is "stuff") and things with mass have weight when in a gravitational field, such as on Earth. If air didn't have any weight, we wouldn't even have an atmosphere.
Heat alone does not make things fly. However, heating air can affect the movement of objects in the air. For example, hot air balloons rise because the air inside the balloon is heated, making it less dense than the surrounding air, causing the balloon to float upwards.
By expanding them, you create a vacuum inside them; given a portal (your mouth, nose), the vacuum will pull the ambient air in, just as a vacuum cleaner pulls things inside by creating a vacuum.
i pollutes the air pollutes inside peoples lungs and other living things
Umm...I believe it is air! If it were helium there would.....forget it, I'm not going there....
The air pressure inside the bottle will increase as more air is filled up inside. This is because the air molecules are compressed, resulting in higher pressure.
The density of the air inside a hot air balloon is greatest when the air inside is coolest. As the air inside the balloon is heated, it expands and becomes less dense compared to the surrounding air, causing the balloon to rise.
There isn't a sensor inside the air filter.There isn't a sensor inside the air filter.
There are many things that make you float such as a bin or large container turned upside down. The best things that make you float are things with air trapped inside them. These things may be large empty water containers from a water dispencer or lots of bubble wrap or even a coat that has air in the lining.
