    Bromine has a melting point of \[-{{7.2}^{o}}C\] and a boiling point of\[{{59}^{o}}C\]. At what temperature will bromine have a definite volume but no definite shape?

    A) \[{{65}^{o}}C\]                      

    B) \[{{36}^{o}}C\]  

    C) \[-{{26}^{o}}C\]         

    D)        \[98\,\,K\]

    Correct Answer: B

    Solution :

     At a temperature greater than \[-{{7.2}^{o}}C\] but less than\[{{59}^{o}}C\], bromine is a liquid. A liquid has a definite volume but no definite shape, it only takes the shape of the container. Hence, temperature is \[{{36}^{o}}C\] (in this case).
