Pressure inside of a balloon is created by the movement of the air molecules against the inner surface of the balloon. The more air inside the balloon, the more molecules that are hitting the same surface are, so there is more pressure.

When a sound pressure wave propagates in a medium it creates areas of high and low pressures which are respectively known as?

When a sound pressure wave propagates in a medium, it creates areas of high pressure known as compressions and areas of low pressure known as rarefactions.


What type of air pressure creates a tornado?

A low-pressure system creates the conditions for a tornado to form. Tornadoes typically develop when warm, moist air at the surface meets with cool, dry air aloft, causing instability in the atmosphere. This creates a rotating column of air that can intensify into a tornado.


What is the burning material that creates pressure to force the bullet out of a barrel?

Gunpowder, also known as black powder or smokeless powder, is the burning material that creates pressure to force the bullet out of a barrel. When ignited, the gunpowder rapidly generates high-pressure gas, propelling the bullet forward.


Air pressure is affected by which three factors?

Air pressure is affected by altitude, temperature, and humidity. As altitude increases, air pressure decreases. Temperature also affects air pressure: warm air rises and creates low pressure, while cool air sinks and creates high pressure. Humidity can impact air pressure by making air lighter (lower pressure) when it is humid due to the presence of water vapor.


An airplane stays in the air because the air pressure on the top of the wing is less than the pressure on the bottom This creates a phenomenon called what?

This phenomenon is called lift. The pressure difference between the top and bottom of the wing creates an upward force that counteracts gravity, allowing the airplane to stay aloft.
