In the 1700's a number of people investigated gas behavior in the laboratory. Robert Boyle investigated the relationship between the volume of a dry ideal gas and its pressure. Since there are four variables that can be altered in a gas sample, in order to investigate how one variable will affect another, all other variables must be held constant or fixed. Boyle fixed the amount of gas and its temperature during his investigation. He found that when he manipulated the pressure that the volume responded in the opposite direction. For example, when Boyle increased the pressure on a gas sample the volume would decrease. Mathematically, PV = constant value if the gas is behaving as an Ideal Gas. A practical math expression of Boyle's findings is as follows:

P1V1 = P2V2

where the variables with the 1 subscript mean initial values before the manipulation and the variables with the 2 subscript mean final values after the manipulation.

Charles's Law

Jacques Charles investigated the relationship between the Volume of a gas and how it changes with temperature. He noted that the volume of a gas increased with the temperature. Charles's Law states that the volume of a given amount of dry ideal gas is directly proportional to the Kelvin Temperature provided the amount of gas and the pressure remain fixed. When we plot the Volume of a gas against the Kelvin temperature it forms a straight line. The mathematical statement is that the V / T = a constant. For two sets of conditions the following is a math statement of Charles's Law:

V1 / T1 = V2 / T2

Gay-Lussac Law

Gay-Lussac investigated the relationship between the Pressure of a gas and its temperature. At constant Volume, the pressure of a gas sample is directly proportional to the Kelvin Temperature. The relationship is similar to the Volume-Temperature relationship (Charles's Law). The mathematical statement is as follows:

The 3 GasLaws
Introduction
The three gaslaws include: Gay-Lussac’s law, Boyle’s law and Charles’ law. When combined with Avogadro’s law the three laws can be generalized by the ideal gaslaw. Gases possess observable properties which include, mass, pressure (P), thermodynamic...

...Perfect gas and Ideal gas Defined
A ‘perfect gas’ is a theoretical gas that differs from real gases in a way that makes certain calculations easier to handle. Its behavior is more simplified compared to an ideal gas (also a theoretical gas).
An ‘ideal gas’ is defined as a gas having no forces of intermolecular attraction. The gases which follow the gas...

...Gaslaws have an impact on several aspects of our lives. The S.T.E.M I decided to explore deals a great deal in thermodynamics in the gaslaw I chose chemistry. First off I have to explain what is the broad practice of chemistry. Chemistry, a branch of physical science, is the study of the composition, properties and behavior of matter. Chemistry is concerned with atoms and their interactions with other atoms, and particularly with the...

...*GasLaws*
One of the most amazing things about gases is that,
despite wide differences in chemical properties, all the
gases more or less obey the gaslaws. The gaslaws deal
with how gases behave with respect to pressure, volume,
temperature, and amount.

Gases are the only state of matter that can be compressed
very tightly or expanded to fill a very large space. Pressure is
force per unit area,...

ABSTRACT
Gases behave in a similar way over a wide variety of conditions because to a good approximationthey all have molecules which are widely spaced, and nowadays the equation of state for an ideal gas isderived from kinetic theory. The combined gas...

...GasLaws Lab
Introduction:
The four basic physical properties of a gas sample are pressure, volume, temperature, and number of moles. The volume simply indicates the volume of the container since a gas will take up all space available to it. The temperature indicates the average kinetic energy of the gas particles. For gases, the temperature must be converted to the Kelvin unit. The pressure of the gas...

...pressure, volume, and temperature were constant across types of gas. These early laws gave rise to the combined gaslaws and the ideal gaslaws.
Charles’s Law
Charles’ Law shows a direct relationship between the volume of a gas and the temperature of the gas. As with most things, as the temperature of a gas increases so does the volume....
