    Two glass bulbs A and B are connected by a very small tube having a stop-cock. Bulb A has a volume of 100 cm3 and contained the gas while bulb B was empty. On opening stop-clock, the pressure fell down to 40%. The volume of the bulb B must be

    A)  \[75c{{m}^{3}}\]

    B)  \[125c{{m}^{3}}\]

    C)  \[150c{{m}^{3}}\]       

    D)  \[250c{{m}^{3}}\]

    Correct Answer: C

    Solution :

     \[100\times p={{V}_{2}}\times \frac{40p}{100}\] \[{{V}_{2}}=250cc\] (Total volume) Volume of bulb \[B=250-100=150\text{ }cc\]
