![]() ![]() ![]() In his experiment, he calculated that the increase in volume with every degree equals 1/273.15 times of the original volume. This means that with the increase in temperature the volume shall increase while with decreasing temperature the volume decreases. According to his findings, at constant pressure and for constant mass, the volume of a gas is directly proportional to the temperature. He did this analysis to understand the technology behind the hot air balloon flight. Jacques Charles in 1787 analyzed the effect of temperature on the volume of a gaseous substance at a constant pressure. Boyle’s law can be graphically represented as follows: In other words, the pressure applied is directly proportional to the density of the gas. When a pressure is applied to the gaseous substance, these molecules come closer and occupy a lesser volume. In a free state, a gaseous substance occupies a larger volume of the container due to the scattered molecules. The reason being the intermolecular force between the molecules of the gaseous substance. So according to Boyle’s law, if the pressure is doubled then at constant temperature the volume of that gas is reduced to half. The initial volume and initial pressure here is p 1 and V 1 then according to Boyle’s law: p 1×V 1 = p 2×V 2 = constant (k 1) Now, if a fixed mass of gas undergoes an expansion at constant temperature then the final volume and pressure shall be p 2 and V 2. K 1 here is a proportionality constant, V is the Volume and p is the pressure. In other words according to Boyle’s law volume is inversely proportional to pressure when the temperature and the number of molecules are constant. It states that under a constant temperature when the pressure on a gas increases its volume decreases. Robert Boyle conducted an experiment on gases to study the deviation of its behaviour in changed physical conditions. Behaviour of Real Gases – Deviations From Ideal Behaviourīoyle’s law states the relation between volume and pressure at constant temperature and mass.Let us study more about the important gas laws! Browse more Topics under States Of Matter hence gas laws are relations between these variables. The variables of state like the Pressure, Volume and Temperature of a gas depict its true nature. Gas laws are an analysis of this behaviour of gases. But with a slight change in physical conditions like pressure, temperature or volume these show a deviation. All gases generally show similar behaviour when the conditions are normal. ![]()
