    At \[27{}^\circ C\] a sample of ammonia gas exerts a pressure of 5.3 atm. What is the pressure when the volume of the gas is reduced to one-tenth of the original value at the same temperature?

    A) 0.53 atm          

    B) 5.3 atm

    C) 53 atm             

    D) None of these

    Correct Answer: C

    Solution :

    [c] \[{{P}_{1}}{{V}_{1}}={{P}_{2}}{{V}_{2}}\] \[{{V}_{1}}=V,{{V}_{2}}=V/10\] \[\frac{5.3\,atm}{{{P}_{2}}}=\frac{\frac{V}{100}}{V};{{P}_{2}}=5.3\times 100=53\,atm\]
