The real coefficient of volume expansion of glycerine is $0.000597\, per°C$ and linear coefficient of expansion of glass is $0.000009\, per°C.$ Then the apparent volume coefficient of expansion of glycerine is

A

$0.000558 \,per°C$

B

$0.00057 \,per°C$

C

$0.00027 \,per°C$

D

$0.00066\, per°C$

Solution

(b) As we know ${\gamma _{{\rm{real}}}} = {\gamma _{{\rm{app}}{\rm{.}}}} + {\gamma _{{\rm{vessel}}}}$

$\Rightarrow$ ${\gamma _{{\rm{app}}{\rm{.}}}} = {\gamma _{{\rm{glycerine}}}} – {\gamma _{{\rm{glass}}}}$

$ = 0.000597 – 0.000027 = 0.00057°C^{-1}$
