# Title: Gas Laws Part 1

• Gas laws are those laws which describe the properties of gases with respect to temperature, moles, volume, and pressure.
• The gas laws are a group of laws that govern the behavior of gases by providing relationships between the following:
• The volume occupied by a gas.
• The pressure exerted by a gas on the walls of its container.
• The absolute temperature of the gas.
• The amount of gaseous substance (or) the number of moles of gas.
• The laws related to all these properties and help in the approximation for most of the gases.
• In normal condition all gasses show similar behavior, variation occurs when the physical parameters such as temperature, pressure and volumes are slightly altered.
• The gas laws were developed towards the end of the 18th century by numerous scientists (after whom, the individual laws are named) .
• Law basically describes the deviations in the behavior of gases.
• Gas laws were formulated at the end of the 18th century and were a result of many different science experiments.
• There are many several types of gas laws, proposed by different scientists in different periods.
• While the laws have been named after the scientist who discovered it.
• Important thing to be aware of here is to understand the relationship between the different laws.
• Boyle՚s law: which provides a relationship between the pressure and the volume of a gas
• Charle՚s law: which provides a relationship between the volume occupied by a gas and the absolute temperature
• Gay-Lussac law: which provides a relationship between the pressure exerted by a gas on the walls of its container and the absolute temperature associated with the gas
• Avogadro՚s law: which provides a relationship between the volume occupied by a gas and the amount of gaseous substance
• Combined Gas law

• Boyle՚s law gives the relationship between the pressure of a gas and volume of the gas at a constant temperature.
• Boyle՚s law, also called Mariotte՚s law, a relation concerning the compression and expansion of a gas at constant temperature.
• Basically, the volume of a gas is inversely proportional to the pressure of a gas at a constant temperature.
• Boyle՚s law equation is written as:

• Where V is the volume of the gas,
• P is the pressure of the gas
• K1 is the constant.
• Boyle՚s Law can be used to determine the current pressure or volume of gas and can be represented also as;
