Solution

The correct option is B $0.000557 {p e r}^{o} C$
Coefficient of volume expansion of glycerine $= 0.000597 {p e r}^{o} C$
Coefficient of volume expansion of glass $= 3 \times 0.000009 = 0.000027 {p e r}^{o} C$
Apparent coefficient of volume expansion
$= 0.000597 - 0.000027 = 0.00057 {p e r}^{o} C$
