A10-g mass of krypton occupies 15.0 l at a pressure of 210 kpa what is the volume of the krypton when the pressure is increased to 790 kpa

According to Boyle's Law," the volume of a fixed mass of gas is inversely proportional to the pressure applied on it".

Mathematically,
                                   P₁ V₁  =  P₂ V₂      (1)

Data Given:
                  Initial Volume  =  V₁  =  15.0 L

                  Initial Pressure  =  P₁  =  210 kPa

                  Final Pressure  =  P₂  =  790 kPa

                  Final Volume  =  V₂  =  ?

Solving eq. 1 for V₂,

                                    V₂  =  P₁ V₁ / P₂

Putting Values,
                                    V₂  =  (210 kPa × 15.0 L) ÷ 790 kPa

                                    V₂  =  3.98 L

Its trait is different and it the organism survive
