When you blew between the balloons a they move towards each other B pressure between the balloons reduces?

When you blew between the balloons a they move towards each other B pressure between the balloons reduces?

Hint: Blow of air means that the air gains velocity. Nonzero velocity means change in pressure. Blowing between two balloons reduces the pressure between them.

When air is blown between two identical inflated balloons they move towards each other which property of air is described by this activity?

When air is blown in between two balls suspended close to each other with high speed, a low pressure is created between the balls which is much less than the atmospheric pressure beyond the balls. Due to this, balls are attracted towards each other. This is according to Bernoulli’s theorem.

Why is hair attracted to balloon?

Because electrons are negatively charged, the balloon acquires a negative charge, while the hair, with its loss of negative charges, now has a net positive charge. So the balloon and hair have opposite charges, and opposite charges attract each other. That’s why the hair gets pulled toward the balloon (Figure 2).

Why is the balloon electrified?

This is because the rubbing creates a negative charge that is carried by electrons. The electrons can build up to produce static electricity. Similarly, when you rub a balloon on your head it causes opposite static charges to build up both on your hair and the balloon.

Why do the balloons get attracted towards each other when the air is blown between them?

Ans. When air is blown in between two balls suspended close to each other with high speed, a low pressure is created between the balls which is much less than the atmospheric pressure beyond the balls. Due to this, balls are attracted towards each other.

Why are balloons pushed closer to each other when air is blown in the space between them?

By blowing air forcefully between the balloons you created an area of low pressure. The air pressure between the balloons decreased in comparison with the air pressure around the rest of the balloons. Because higher pressure pushes toward lower pressure the balloons were pushed toward each other.

What happens to the balloon flow of air?

The collision of these air particles with the walls creates a high-pressure environment inside the balloon relative to the atmospheric pressure around it. This is why when a balloon is released, the high-pressure air flows out of the balloon to the low-pressure air surrounding it: “Winds blow from high to low.”

Why do strands of your hair stand after you take off your hat?

As you remove your hat, electrons are transferred from hat to hair, creating that interesting hairdo! Remember, objects with the same charge repel each other. Because they have the same charge, your hair will stand on end. Your hairs are simply trying to get as far away from each other as possible!

What will happen if you rub a balloon in your hair?

Rubbing the balloon onto your hair or onto the wool fabric adds electrons to the balloon and causes the balloon to become negatively charged. Your positively charged hair is attracted to the negatively charged balloon and starts to rise up to meet it.

What happens to the balloons after rubbing it your hair?

What will happen when air is blown in between two balls suspended freely?
