where the index i denotes the ith species, c is the concentration ( mol / m < sup > 3 </ sub >), R is the universal gas constant ( J /( K mol )), T is the absolute temperature ( K ), and μ is the chemical potential ( J / mol ).

In fact, assuming an ideal gas, the speed of sound c depends on temperature only, not on the pressure or density ( since these change in lockstep for a given temperature and cancel out ).

Along the red portion of the isotherm which is unstable ; the Van der Waals equation fails to describe real substances in this region because the equation always assumes that the fluid is uniform while between a and c on the isotherm it becomes more stable to be a coexistence of two different phases, a denser phase which we normally call liquid and a sparser phase which we normally call gas.

where < i > P < sub > V </ sub ></ i > is the vapor pressure ( flat portion of the curve ), < i > V < sub > L </ sub ></ i > is the volume of the pure liquid phase at point a on the diagram, and < i > V < sub > G </ sub ></ i > is the volume of the pure gas phase at point c on the diagram.

It follows that systems with volumes intermediate between these two points will consist of a mixture of the pure liquid and gas with specific volumes equal to the pure liquid and gas phases at points a and c.

where k is a temperature-dependent constant, p is the partial pressure and c is the concentration of the dissolved gas in the liquid.

where p is the partial pressure of the solute in the gas above the solution, c is the concentration of the solute and k < sub > H </ sub > is a constant with the dimensions of pressure divided by concentration.

* From c to d. The displacer moves to the right with the cold head connected to the lp side of the compressor forcing the cold gas to pass the regenerator, while taking up heat from the regenerator.

His experiments were numerous and accurate and made upon a variety of substances ; having obtained the gas from wood, peat, different kinds of coal, oil, wax, & c. he quantified the intensity of the light from each source.

Figure 1 shows the results of the solution to this equation for α = 3 / 2, with k = ε < sub > c </ sub >= 1 which corresponds to a gas of bosons in a box.

While working on the olefins he noticed that a change takes place in the density of the vapor of amylene hydrochloride, hydrobromide, & c, as the temperature is increased, and in the gradual passage from a gas of approximately normal density to one of half-normal density he saw a powerful argument in favor of the view that abnormal vapor densities, such as are exhibited by sal-ammoniac or phosphorus pentachloride.

Gee Jon ( c. 1895 – February 8, 1924 ) was a Chinese national who was the first person in the United States to be executed by lethal gas.
