A child sits on a partially filled balloon and decreases the volume by half. What happens to the pressure inside of the balloon?
A. It increases
For the same balloon, how does the density inside the balloon change?
A. increases
A scientist takes a small, partially inflated balloon out of liquid nitrogen (at a very low temperature). As the balloon rests on the table, it begins to grow in size. Which statement(s) best explains why the balloon grows?
B. The air warms and increases particle movement. Increased particle movement leads to increased volume.
C. Increased temperature means increased volume as long as the container is flexible.

The child is putting pressure on the balloon, and squishing particles together when he/she sits on it, thus increasing pressure. Since particles are being squished closer together, density also increases.
Inflated objects will grow in size when the air inside is hotter. This is because particles move more rapidly. An example would be bike tires being more inflated under hot conditions.
One mole of any gas at standard temperature and pressure (STP) will occupy 22.4 L. If pressure increases, the volume decreases, and vice versa. If moles decreases, so will the volume, and vice versa.
Here are photos of Edge just incase.
The pressure inside of the balloon will Increase. Hence The correct option is (A).
According to this law, the pressure (p) of a given quantity of gas varies inversely with its volume (v) at constant temperature; i.e., in equation form,
pv = k
Where K = constant.
If we consider that temperature of the gas which filled inside the balloon is constant.
We know that , at constant temperature
P₁V₁ = P₂V₂
Given that
V₂ = V₁ / 2
P₂ = P₁V₁/V₂
P₂ = P₁V₁/V₁/2
P₂ = 2P₁
Therefore, the pressure inside the balloon will become double.Hence The correct option is (A).
