a.It increases
b.It decreases
c.It stays the same

Answer 1

Answer: First: it increases

Second: increases

Answer 2

a.It increases

Step-by-step 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

`V_2=(V_1)/(2)`

`P_2=(P_1V_1)/(V_2)`

`P_2=(P_1V_1)/((V_1)/(2))`

P₂ = 2 P₁

Therefore the pressure inside the balloon will become double.

Therefor the answer will be a.
