mercury thermometer

A mercury thermometer measures temperature by measuring the volume expansion of a fixed mass of liquid mercury due to a change in density (see Problem 1.91). Find the relative change (%) in volume for a change in temperature from 10◦C to 20◦C.

Problem 1.91

The density of mercury changes approximately linearly with temperature as ρHg = 13 595 − 2.5 T kg/m3 (T in Celsius), so the same pressure difference will result in a manometer reading that is influenced by temperature. If a pressure difference of 100 kPa is measured in the summer at 35◦C and in the winter at −15◦C, what is the difference in column height between the two measurements?
