GASES

What is a gas? How is it different from steam?

Gases are defined as a state of aggregation of matter in which it does not have a determined form due to the dispersion and free mobility of the molecules.

NOBLE GASES:

Noble gases are a group of chemical elements that have very similar properties. They are odorless, colorless and have low chemical reactivity. They have a place in group 18 of the periodic table under the same name.

Equations of state of gases:

The main problem we face when working with gases is finding an equation that takes into account pressure, temperature and volume. There are always two independent variables and one dependent variable. The first equation was then: P.V=n.R.t(1) where P is the absolute pressure of the system, V is the volume of the system, n is the number of moles of the gas, R is the ideal gas constant, and T is the temperature at absolute scales. This law is used to perform calculations with ideal gases.

Equations of state for real gases:

When the gas begins to have extreme conditions of temperature decreases or pressure increases, it should be considered a real gas. P.V / R.T =1

General gas law:

This law combines the laws already established by Boyle, Charles and Gay-Lussac where each variable already mentioned: volume, temperature and pressure are found in the same general equation. Charles establishes that volume and temperature under constant pressures are directly proportional while Boyle maintains that pressure and volume are inversely proportional to each other at constant temperature. Gay-Lussac establishes direct proportionality between temperature, pressure and volume. As a result: P.V/T = k

Gas fields:

Natural gas is part of the hydrocarbons, it is a mixture of light gases that contains a variable amount of alkanes, carbon dioxide, nitrogen, sulfuric acid, helium among others. When animal and plant remains enter a state of decomposition and are affected by high temperatures underground, what we know as natural gas is produced.
