Answer:
9L
Explanation:
Given parameters:
Initial volume V₁ = 3.6L
Initial pressure P₁ = 2.5atm
Final pressure P₂ = 1atm
Unknown:
Final volume V₂ = ?
Condition: constant temperature = 25°C
Solution:
This problem compares the volume and pressure of a gas at constant temperature.
This is highly synonymous to the postulate of Boyle's law. It states that "the volume of a fixed mass of gas is inversely proportional to the pressure provided that temperature is constant".
Mathematically;
P₁V₁ = P₂V₂
where P and V are pressure and volume
1 and 2 are initial and final states
Input the parameters and solve for V₂;
2.5 x 3.6 = 1 x V₂
V₂ = 9L
