Gas Laws & Ideal Gas Equation

How much should the pressure be increased in order to reduce the volume of a given mass of gas by 5%5\% at the constant temperature?

Show answer and solution

Answer: (c)

  1. Boyle's law: P∝1VP \propto \dfrac{1}{V} at constant TT.
  2. V′=0.95V⇒P′=P0.95=1.0526PV' = 0.95V \Rightarrow P' = \dfrac{P}{0.95} = 1.0526P
  3. So the answer is (c) 5.26%5.26\%.
