When molecules of air are pushed together, they form an area of high pressure which is called compression. If the compression is cyclonic, it is called a node.

What are area where air is pushed together in vibrations called?

Compression


Explain how sound travels?

Sound travels in waves called sound waves and they look like this )))))))))))))))))))))) except they are invisible


Area in which sound waves are pushed together?

This question is misguided. It is not the sound waves which are apart, but the particles of the medium. A place where the particles are further apart is called a rarefaction. Where they are crowded together is called a compression.


Can you explain why an inflated balloon shoots off when air is released?

The air inside the balloon is at a higher pressure than atmospheric pressure so the gas molecules inside the balloon are closer together on average than gas molecules outside the balloon. This means that the repulsive forces between the gas molecules inside the balloon are greater than the repulsive forces between the gas molecules outside it. When the balloon is opened, the gas molecules in the open end at the border between the higher pressure interior and lower pressure exterior will experience a greater repulsive force from the gas molecules inside the balloon than the molecules on the outside. This means that they experience a net force pushing them out of the balloon. As these gas molecules are pushed out by the gas inside the balloon, they push back on it with an equal and opposite force (due to Newton's 3rd Law of Motion). This equal and opposite reaction force causes the gas in the balloon to be pushed in the opposite direction to the escaping gas, which in turn pushes the balloon. As more and more gas escapes, the reaction force on the balloon continues to accelerate it, making it shoot off, until enough gas has escaped for the pressure inside the balloon to have dropped to the same level as the pressure outside the balloon.

What does airpressure mean?

Air Pressure means the measure of the force with which air molecules pushed on a surface.


If the pressure inside the lungs decreases outside air is pushed into the airways by what?

The pressure inside the lungs decreases as the ribcage moves out and up. Air from outside basically gets pushed in by other air molecules due to the pressure gradient (air moves from a high pressure to a low pressure)

well, when something is pushed together, it's called compression so probably a 'Compressed spring'.

It should get pushed in slightly as the molecules are moving slower therefore the pressure inside is reduced

Do balloons really pop under pressure?

yes! because all the air is pushed together forcing it to burst!
