The Combined Gas Law describes the relationship between temperature, volume, and pressure. The relationship between pressure and volume is P1V1 = P2V2, otherwise known as Boyle’s Gas Law. The relationship between temperature and volume is stated in Charles 's Gas Law, which states V1/T1 = V2/T2. The relationship between temperature and pressure, also known as Gay Lussac 's Gas Law, is P1/T1 = P2/T2. The Combined Gas Law is a combination of Boyle’s, Charles’s, and Gay Lussac 's Gas Laws, resulting in P1V1/T1 = P2V2/T2 (Chemistry: The Physical Setting). The particles in gases move very quickly and freely, constantly colliding into its surroundings and each other. According to the Kinetic Molecular Theory and based on Boyle’s Gas Law, the pressure and volume of a gas are proportional. If the gas is more confined, then the movement of the same number of gas particles will increase when colliding in a smaller area, ultimately causing the collisions to increase, and thereby the pressure. Based on Charles’s Gas Law, an increase in temperature will result in an increase of the average kinetic energy of molecules. This causes the movement of particles to be faster, therefore causing more collisions into its surroundings and each other; thus, increasing the pressure of the gas. Gay Lussac’s Gas Law states that as the temperature of a gas increases, the pressure increases as well. This can be explained in terms of the Kinetic Molecular Theory; as the temperature of a gas increases, so…
