Question

Please help!!

What is the new pressure of a 2.5 liter balloon if the original volume was 6.2
liters at a pressure of 3.3 atm?

.12 atm
4.7 atm
8.2 atm
1.3 atm

Answer 1

P₂ = 8.2 atm

Step-by-step explanation:

Given data:

Final pressure = ?

Final volume = 2.5 L

Initial volume = 6.2 L

Initial pressure = 3.3 atm

Solution:

The given problem will be solved through the Boly's law,

"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"

Mathematical expression:

P₁V₁ = P₂V₂

P₁ = Initial pressure

V₁ = initial volume

P₂ = final pressure

V₂ = final volume

Now we will put the values in formula,

P₁V₁ = P₂V₂

3.3 atm × 6.2 L = P₂ × 2.5 L

P₂ = 20.46 atm. L/2.5 L

P₂ = 8.2 atm
