Determine the pressure required to compress a gas in a cylinder initially at 20^oC and at a pressure of 1.03 x 10^-5 to one-eighth of its original volume.

      

Determine the pressure required to compress a gas in a cylinder initially at 20^oC and at a pressure of 1.03 x 10^-5 to one-eighth of its original volume.

P₁ = 1.03 x 10⁵, let the original volume be V₁,

then final volume, V₂ = $\frac{1}{8}V_1$

P₁V₁ = P₂V₂,

P₂ = $\frac{P_1V_1}{V_2}$

= $\frac{(1.03\times 10^-5)V_1}{V1/8}$ = 8.24 x 10⁵
