Question

The absolute coefficient of expansion of a liquid is 7 times that the volume coefficient of expansion of the vessel. Then the ratio of absolute and apparent expansion of the liquid is

• A.
• B.
• C.
• D. None of these

Answer 1

The correct option is B

Apparent coefficient of Volume expansion $\gamma {}_{app.}$ = $\gamma {}_L$ - $\gamma {}_s$ = 7 $\gamma {}_s$ - $\gamma {}_s$ = 6$\gamma {}_s$(given $\gamma {}_L$ = 7 $\gamma {}_s$ )
Ratio of absolute and apparent expansion of liquid $\frac{{\gamma }_L}{{\gamma }_{app.}}=\frac{7{\gamma }_s}{6{\gamma }_s}=\frac{7}{6}$.
