Question

375cm of a gas has a pressure of 770mmHg.find its volume if the pressure is reduced to750mmHg.

Answer 1

$\huge\star\underline\blue {Answer:-}$

Given

initial volume = 375cm^3

initial pressure = 770mm of Hg

Final pressure = 750 mm of Hg

let v be the final volume

By Boyle's law

$p1v1 = p2v2 \\ 770 \times 375 = 750 \times v \\ v = \frac{770 \times 375}{750} \\ v = 385 {cm}^{3}$

Hence the final volume is 385 cm^3
