    The real coefficient of volume expansion of glycerine is \[0.000597\text{ }per\text{ }{}^\circ C\] and linear coefficient of expansion of glass is\[0.000009 per {}^\circ C\]. Then the apparent volume coefficient of expansion of glycerine is                      

    A) \[0.000558\text{ }per\text{ }{}^\circ C\]

    B)   \[0.00057\text{ }per\text{ }{}^\circ C\]

    C) \[0.00027\text{ }per\text{ }{}^\circ C\]  

    D) \[0.00066\text{ }per\text{ }{}^\circ C\]

    Correct Answer: B

    Solution :

    As we know \[\Rightarrow \,\,\,\,\,{{\gamma }_{app.}}={{\gamma }_{glycerine}}+{{\gamma }_{g}}_{lass}\] \[=\,\,0.000597-0.000027=0.00057/{}^\circ C\]
