# Problem on Theory of Gases

A chamber of volume $$1000\text{ cm}^3$$ is evacuated by a pump at constant temperature whose evactuation rate is equal to $$50\text { cm}^3\text{ s}^{-1}$$.

Find the time in which the pressure of the chamber reduces to $$e$$ times the original pressure.

Take $$e = 2.7182 \ldots$$.
