If the coefficient of volume expansion of glass would have been equal to the coefficient of real expansion of mercury, a mercury thermometer would not be active-explain.

If the coefficient of volume expansion of glass would have been equal

1.	If the coefficient of volume expansion of glass would have been equal to the coefficient of real expansion of mercury, a mercury thermometer would not be active-explain.
