Extracted text: A vessel that contains a gas has two pressure gauges attached to it. One contains liquid mercury, and the other an oil such as dibutyl phthalate. The difference in levels of mercury in the two arms of the mercury gauge is observed to be 9.50 cm. Given density of mercury 13.60 g cm-3 -3 density of oil = 1.045 g cm¯ acceleration due to gravity = 9.806 m s (a) What is the pressure of the gas? (b) What is the difference in height of the oil in the two arms of the oil pressure gauge?
