    If \[20\text{ }c{{m}^{3}}\] gas at 1 atm. is expanded to \[50\text{ }c{{m}^{3}}\] at constant T, then what is the final pressure?

    A) \[20\times \frac{1}{50}\]                        

    B) \[50\times \frac{1}{20}\]

    C) \[1\times \frac{1}{20}\times 50\]             

    D) None of these

    Correct Answer: A

    Solution :

    \[{{P}_{1}}{{V}_{1}}={{P}_{2}}{{V}_{2}}\] \[1\times 20\,\,=\,\,{{P}_{2}}\,\times \,50\] \[{{P}_{2}}\,=\,\,20\,\,\times \,\,\frac{1}{50}\]
