needle is pressing the balloon

When the needle is pressing the balloon, why does it burst with a loud voice?

We often see the colorful balloon decoration at the festivals held at birthdays or on special occasions, which are quite enjoyable in seeing and refreshing our childhood memories. The kids are very excited to see these balloons and they will break it. Feel very rejoicing, from which "pop" sounds.

Have you ever wondered why this happens? Why is the sound of "pop" born when sudden needle is thrown in the balloon? When we throw a needle in chips or any other air packet, the same thing is repeated. Let us try to know the reasons behind this.The reason behind this incident is the elasticity of the balloon.

needle is pressing the balloon

The balloon is made of flexible material such as rubber, latex, nylon, polycleroprene etc. due to which the flexibility increases when filling the air in the balloon and it becomes larger than its original size. In addition, the pressure inside the air balloon is externally More, which creates a difference between the internal air pressure of the balloon and the internal air pressure of the balloon.

Rubber molecules are made up of very long molecules in the balloon, which are connected together. The elastic / flexibility of the balloon is due to nature, it increases to a certain extent. But if that limit is crossed, then The stress increases significantly due to which the balloon breaks down and the sound of "pop" comes out. In fact when a balloon filled with air bursts, it breaks into two pieces, but when we Switch to fill so much air that he should not burst, it is divided into several pieces .

When the needle throws in the air balloon, why does the sound of "pop" arise? Let us know the reasons for this.

When we punch a needle in a balloon, a small hole is formed on its surface. Now if this balloon is blown slowly, then the "pop" sound will not come out, because through this hole the air will slowly come out and The balloon will return to its original shape. But when a balloon is blown in its maximum size, its polymer molecules are very stressed and the surface of the balloon At the same time, when a small hole is made on the surface of the balloon, the rubber of the balloon can not be equally dragged in all directions, due to this, the total force gets away from the hole and Increases the size of the hole due to stretching of the surface, causing the balloon to burst with the sound of "pop".

We should not forget that after the rapid expansion of the air inside the balloon, there is a sudden change in pressure due to the sound of "pop" and this whole event takes only a few seconds of seconds.
