Achild sits on a partially filled balloon and decreases the volume by half. what happens to the pressure inside of the balloon?

The pressure inside of the balloon increases by half

Explanation:

We can think of the balloon as a container of air ,which is a gas with a determinate volume and pressure.

According to Boyle's law the volume of a gas is inversely proportional to its pressure.

For example, if a balloon volume is 3 liters  and the pressure inside the balloon 20 pascal and a man inflates the balloon up to 6 liters the pressure inside the balloon now is 10 pascal.

When a tank with 40 liters of nitrogen and 100 pascal of inner pressure is  compressed to 200 pascal of pressure, the volume goes down to 20 liters

So  when the volume increases the pressure decreases and vice versa

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be

a electronegativity decreases beacuse the size of nucleus is bigger.
