Question

Two identical spherical balloons have been inflated with air to different sizes
and connected with the help of a thin pipe. What do you expect out of the
following observations?
(i) The air from smaller balloon will rush into the bigger balloon till whole
of its air flows into the later.
(ii) The air from the bigger balloon will rush into the smaller balloon till the
sizes of the two become equal.
What will be your answer if the balloons are replaced by two soap bubbles of
different sizes.

Answer 1

Answer:

Option ii is correct

Explanation:

Answer 2

Answer:

The correct answer is option (i), i.e., the air from the smaller balloon will rush into the bigger balloon till whole of its air flows into the bigger one.

In case of soap bubbles, air fist goes to smaller to bigger and again from bigger to smaller until it vanishes.

Explanation:

The air from the smaller balloon will rush into the bigger balloon till whole of its air flows into the bigger one because of the pressure differences.

As we know, air moves from the higher pressure to lower pressure. So, here in the cases of both balloons, the pressure in the more inflated is obliviously higher.

For Soaps:

We know for bubbles pressure is given by,

$\text { Pressure }=\frac{4 \times \text { Tension }}{\text { radius }}$

Or, pressure is indirectly proportional to radius.

So, air fist goes to smaller to bigger and again from bigger to smaller until it vanishes.
