1. If 22.5 L of nitrogen at 1.25 atm are compressed to 2.10 atm at constant temperature. What is the new

volume?

V₂ = 13.4 L

Explanation:

Given dа ta:

Initial volume of gas = 22.5 L

Initial pressure = 1.25 atm

Final pressure = 2.10 atm

Final 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

1.25 atm * 22.5 L = 2.10 atm * V₂

V₂ = 28.125 atm. L / 2.10 atm

V₂ = 13.4 L
