a 15.0 L tank of gas is contained at a high pressure of 8.20*10^4. The tank is opened and the gas expands into an empty chamber with a volume of 6.00*10^4 L. Calculate the new pressure of the gas.

Answer:

20.5torr

Explanation:

Given parameters:

V₁  = 15L

P₁  = 8.2 x 10⁴torr

V₂ = 6 x 10⁴L

 

Unknown:

P₂  = ?

 

Solution:

To solve this problem we have to apply the claims of Boyle's law.

Boyle's law is given mathematically as;

            P₁ V₁   = P₂V₂

 

where P₁ is the initial pressure

          V₁ is the initial volume

           P₂ is final pressure

           V₂ is final volume

 

   8.2 x 10⁴  x 15  = P₂  x 6 x 10⁴

 

         P₂  = 20.5torr
