The heights of mercury in a manometer are 2 cm and 8 cm. Find the pressure of the gas in the cylinder? Patm=105 N m−2
The density of mercury, ρm = 13600 kg m−3. Acceleration due to gravity, g=10 m s−2
A gas occupies a volume of 2.5 L at 9×105Nm−2. Calculate the additional pressure required to decrease the volume of the gas to 1.51. Assume temperature is constant.
