a 15 L tank of gas has a pressure of 8.20*10^4 and the new pressure is 7.00*10^4 what is the new volume

V₂ =17.57 L

Explanation:

Given data:

Initial volume = 15 L

Initial pressure = 8.20×10⁴ atm

Final pressure = 7.00×10⁴ atm

New volume = ?

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

8.20×10⁴ atm × 15 L = 7.00×10⁴ atm × V₂

V₂ =123×10⁴ atm. L/7.00×10⁴ atm

V₂ = 17.57 L
