From the experiments reported in the previous chapter we were able to determine that a very small amount of liquid was sufficient to give a considerable volume of vapor.

Several physical and chemical studies required the knowledge of the volume of this expansion; in other words, that we could determine the volume of vapor that could be given by a given weight or by a given volume of each liquid. But, this determination seemed quite difficult because the expansion of the vapor was substantial. Unfortunately, it was not possible to recondense in one mass the liquid used to generate it.

Fortunately, M. Gay-Lussac eluded this difficulty by reversing it, in other word, by determining the volume of vapor that can be produced by a given volume of liquid. Gay-Lussac blows small glass bubbles BB, Fig. They appear in the upper righthand corner of Fig. We first weigh one of the little. When the small bubble is mostly full, the spout is sealed with a torch. This procedure does not change the composition of the glass but simply the shape of the bubble.

We then weigh the filled bubble again and by subtracting the weight of the glass shell previously weighed, we obtain the weight of the liquid that it contains. We will soon see how we can deduce its volume. To now transform all this liquid into vapor, M. Gay-Lussac uses an apparatus similar to the one M. Dalton used to observe the tension of vapors under vacuum.

He uses a long narrow glass dome VV, Fig. He fills it with mercury and puts it upside-down and then he introduces the small bubble filled with liquid B. The bubble reaches the top of the tube. We now vaporize it. To do so, M. Gay-Lussac covers the dome with a glass envelope MM longer than the tube so its lower portion is plunged into the mercury. He fills the cylinder with water and the dome is then covered.

The apparatus is placed on on a stove FF and a fire is lighted up. The liquid in the the bubble expands and breaks the glass shell, spreads at the top of the dome and soon becomes vapor. The temperature is increased until the water in the cylinder is boiling. Gay-Lussac operates to be as accurate as possible. The sides of the shallow basin vv are made of cast-iron are straight and leveled horizontally.

He sets on the side a ruler made of copper cc with a garaduated rod T set vertically so its tip barely touches the surface of the mercury outside. A marker H that goes up and down along the vertical rod is set at the same level as the mercury inside the dome. The elevation of mercury can the be measured precisely. The difference between the height of the mercury column and the atmospheric pressure measured in the same units represents the elastic force of the vapor contained in the dome.
