Who invented ideal gas law




















The fundamental laws that govern gas behavior were discovered sequentially by men and women who made incremental contributions to development of our understanding of the behavior of gasses. Each in turn, contributed to this growing body of knowledge. This is a story of pneumatic science, and it is representative of the story of science in general.

Ponder this. It was mentioned that gasses are mechanic in nature, what does it mean by this? How is it proven? How do we manipulate the Ideal Gas Law for practical purposes, considering the variables involved? Have we applied such things? The Ideal Gas Law implies that in practice, gasses do not perform as expected. This is not surprising as the many variables pressure, volume, temperature do not react to each other's inputs immediately or perfectly.

Volatile compounds have a high vapor pressure at room temperature and are vaporized at low temperatures. Thus, when the Dumas tube containing the volatile liquid is placed in boiling water, the liquid vaporizes and forces the air out of the tube, and the tube is solely filled with vapor. When the tube is removed from the water bath and left at room temperature, the vapor condenses back to a liquid. Since mass is conserved, the mass of the liquid in the tube is equal to the mass of the gas in the tube.

Using the known mass and volume of the gas, along with the known water bath temperature and room pressure, the moles and therefore molecular weight of the gas can be calculated using the ideal gas law. Here, three assumptions are made: 1 the vapor is acting ideally, 2 the volume of the tube does not vary between the room temperature and the working temperature, and 3 the gas and the water bath are at thermal equilibrium.

Assumptions of the Ideal Gas Law The ideal gas law assumes that gases behave ideally, meaning they adhere to the following characteristics: 1 the collisions occurring between molecules are elastic and their motion is frictionless, meaning that the molecules do not lose energy; 2 the total volume of the individual molecules is magnitudes smaller than the volume that the gas occupies; 3 there are no intermolecular forces acting between the molecules or their surroundings; 4 the molecules are constantly in motion, and the distance between two molecules is significantly larger than the size of an individual molecule.

References Kotz, J. Gay-Lussac, J. The ideal gas law is an equation of state that is very important and fundamental in thermodynamics.

It is found by combining the laws of Boyle, Charles, and Gay-Lussac, into one elegant equation as follows below. All gases do not have the same mass so to simplify matters, we would like to have a constant that is the identical for all of them. For this reason, we convert m into a proportionality constant using a mole. R is a constant of proportionality called the universal gas constant , and in accordance with its name it is the same for all gases. Mathematically, he found that the pressure times the volume equaled a constant.

If we double the pressure, then we cut the volume in half. Boyle is often considered to be the first modern chemist and he was ahead of his time. It was nearly years before the next advance was made. This is a transcript from the video series Understanding the Misconceptions of Science. Watch it now, Wondrium. In , French chemist Jacques Charles was experimenting on the relationship between the volume and temperature of a gas.

If you doubled the temperature of a gas, you doubled its volume. Mathematically, you can write this as volume divided by temperature as a constant. And, by the way, to do this, you need to express the temperature in units of kelvin.

In the kelvin scale, water freezes at Talking about the history of the different temperature scales is very interesting, but it would be off the topic for us.
