A glass flask of volume 360 cc. is completely filled with a liquid of real expansion coefficient $17.7\times {10}^{-5}{/}^0\mathrm{C}\left({\mathrm{\alpha }}_{\text{glass }}=9\times {10}^{-6}{/}^0\mathrm{C}\right)$. When it is heated from 20^oC to 100^oC, volume of liquid expelled is

• A

  3.32 c.c.

• B

  7.15 c.c.

• C

  1.21 c.c.

• D

  4.32 c.c.
