Gas is one of the three states of matter. The gaseous state is composed of a group of molecules that move freely, independent of each other. There are certain properties that define gas and separate the state of matter from the other two states: solid and liquid. Many different energies, forces and quantities greatly influence the behavior of any type of gas. These differences consist of pressure, temperature, volume, and even the number of molecules of a gaseous element. There is a mathematical relationship between all of these properties that affects all properties when only one is changed. Theories that explain this relationship between properties are known as Boyle's and Charles' laws. Kinetic molecular theory, which clarifies how kinetic energy creates the motion of gas molecules, is one of the main theories about gases. And finally, the ideal gas law, which explains the amount of gas used in a chemical reaction. The ideal gas law calculates the ratio of all elements within a chemical reaction and allows you to discover the amount of gas or gases that will be used in the reaction, usually expressed in the form of a linear equation. Gases have some defining properties that distinguish them from the other two states of matter. The atoms of a gas are usually distant from each other and are not affected by the existence of other nearby molecules. They are neither attracted nor repelled by other gas particles. Molecules are constantly moving at extremely high speeds and do not curve in the path they move. When gas molecules collide, they don't stick to each other; however they will simply bounce off each other and continue on a new path. When gases are placed in any type of content... in the center of the paper... of gas particles and molecules, which help define the gas. If the volume of the container is larger, the gas will expand to fill the entire size of the container. All the properties of gases add some complication to the topic, and many formulas, laws, theories and hypotheses allow you to discover any unknown information about the gas, including laws such as Boyle's Law, which compares pressure with volume, Charles's Law, which compares temperature to volume and Avogadro's hypothesis, which compares volume to quantity of gas. Kinetic Molecular Theory is the theory of how the movement of molecules works and how they are powered has been created and improved throughout history, up until the 20th century. The ideal gas law is the connector of the chemical reaction part of gases. Essentially, gases are full of equations, concepts, and properties
