s connected by a fine capillary tube c to thegauge d : this is a wide tube of glass, containing mercury. Themercury reservoir e, attached by rubber tubing, can be raised orlowered till the mercury in d is brought to a fixed mark; thisensures that the volume occupied by the hydrogen is always the… … Fig. 25. the mercury in g has a vacuum above it, and that in d is exposedto the pressure of the hydrogen, the difference in level betweenthe two mercury surfaces measures the pressure of the gas, asexplained in p. 38. The difference in level is read by meansof a scale placed alongside the tubes and…
