Xenon gas measure pd to start sith s volume of 15.5kL. If the the volume changes to the 0?6kL and the pressure becomes 44 Pa, what was the original pressure? Read carefully!

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
