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
b.It decreases
c.It stays the same

Respuesta :

Answer:

a.It increases

Explanation:

Lets take

Initial pressure =P₁

Initial volume = V₁

Final pressure =P₂

Final volume = V₂

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

[tex]V_2=\dfrac{V_1}{2}[/tex]

[tex]P_2=\dfrac{P_1V_1}{V_2}[/tex]

[tex]P_2=\dfrac{P_1V_1}{\dfrac{V_1}{2}}[/tex]

P₂ = 2 P₁

Therefore the pressure inside the balloon will become double.

Therefor the answer will be a.

Answer: First: it increases

Second: increases
