a balloon, a tires, as you said, we actually use air to breath too.
No, if anything other than air, it should be nitrogen.
You can inflate objects and make them bigger by adding air to the object. Balloons and tires are objects that require air in order to inflate and make them bigger.
Objects are more buoyant in water than in air.
Some objects that use compressed air include pneumatic tools (such as nail guns and air compressors), inflatable objects (such as tires and sports balls), pneumatic systems in vehicles, and air cannons in entertainment and industrial applications.
Yes, nitrogen is more stable than air in tires.
Helium is used in airplane tires because it is lighter than air, so it reduces the overall weight of the tires and the wheel assemblies. This can result in fuel savings due to decreased weight of the aircraft. Additionally, helium is less likely to leak out of the tires compared to other gases, helping to maintain tire pressure for longer periods.
Tires create friction, which in turn creates heat. Heated objects expand.
Objects that are round fall faster than objects that are flat because they experience less air resistance. The round shape of an object reduces the surface area in contact with the air, allowing it to move through the air more smoothly and with less drag. This results in round objects falling quicker than flat objects.
An air pump works by creating pressure to force air into an object, such as tires or balloons. When the pump handle is pushed down, it compresses the air inside the pump, increasing its pressure. This high-pressure air is then forced through a nozzle into the object, inflating it.
Objects that float in air are typically those that are less dense than the air around them, such as helium balloons or lightweight objects like feathers. These objects are able to displace enough air to generate an upward force greater than the force of gravity acting on them, allowing them to float.
Objects less dense than air can float on air of that density. Air passing over objects (wings, kites, etc.) can provide lift and support the object. Air moving upwards at a speed equivalent to the terminal velocity of the object in the air stream will support the object. Solid air (frozen at -299oC if you don't care about the Helium or -270oC if you do) will support objects like any other solid.
yes as long as they are cooler than the air around them or other gases solids and liquids!
