Solve the below:
Q: The density of mercury changes approximately linearly with temperature as ΔHg = 13595 - 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?
