You gases they are fluids which, unlike liquids, occupy all the available space of the container where they are confined. The molecules that make up the gases are free to move and interact with each other and with the walls of the container.
THE boyle's lawdetermines that the relationship between pressure and volume of a gas is inversely proportional. The greater the pressure on the molecules, the less space they occupy.
THE Gay-Lussac lawdetermines that the relationship between the volume and temperature of a gas is directly proportional. The higher the temperature of a gas, the greater the agitation of the molecules, which will tend to move apart, increasing the space occupied by them.
Do not stop now... There's more after the advertising ;)
Charles' law determines that the relationship between pressure and temperature of a gas is directly proportional. The higher the temperature of a gas, the greater the molecular agitation. Thus, the incidence of collisions between the molecules and the walls of the container increases, making the pressure of the gas greater.
THE clapeyron equation it synthesizes the three laws presented above and determines a single relationship between the state variables.
T = gas temperature (K).
Nature does not produce gases that have the characteristics of a perfect gas. The ideal gas is a theoretical and useful model for understanding the behavior of gases in face of changes in their characteristics.
