Answer:
17.03Pa
Explanation:
Given parameters:
Initial volume = 15.5kL
Final volume = 6kL
Final pressure = 44Pa
Unknown:
Original pressure = ?
Solution:
The parameters given shows pressure and volume relationship of the given gas. One of the gas laws that predicts pressure - volume relationships is the Boyle's law.
Boyle's law states that "the volume of a fixed mass of gas varies inversely as the pressure changes, if the temperature is constant".
Mathematically,
P₁V₁ = P₂V₂
where P₁ is the initial pressure
V₁ is the initial volume
P₂ is the final pressure
V₂ is the final volume
Input the variables and solve for P₁;
P₁ x 15.5 = 44 x 6
P₁ = 17.03Pa
