The real coefficient of volume expansion of glycerine is `0.000597per^(@)C` and linear coefficient of expansion of glass is `0.000009par^(@)C` . Then the apparent volume coefficient of glycerine is

Options

A. 0.000558 per°C
B. 0.00057 per°C
C. 0.00027 per°C
D. 0.00066 per°C

Answer

B

Explanation

`y_("real") = Y_("app") + 3 alpha`
`rArr y _(app) = 0.000597 - 3 xx 0.00009 = 0.00057//^@C`.
