The bulb and the stem of a mercury-in-glass thermometer contains 1 cm^(3) of mercury up to thezero mark. If the internal diameter of the stem is 0.3 mm, what is the length of a degree celsius on the scale?Coefficient of real expansion of mercury =18 times 10^(-5@)C^(-1) and coefficient of linear expansion of glass =8 times 10^(-6@)C^(-1).

1.	The bulb and the stem of a mercury-in-glass thermometer contains 1 cm^(3) of mercury up to thezero mark. If the internal diameter of the stem is 0.3 mm, what is the length of a degree celsius on the scale?Coefficient of real expansion of mercury =18 times 10^(-5@)C^(-1) and coefficient of linear expansion of glass =8 times 10^(-6@)C^(-1).
