The gas laws were developed in the late s when the scientists understood the relationship between the pressure, volume, and temperature for a sample of gas. These relationships would, in turn, be, approximately, valid for all the gases. Nonetheless, all the gases behave similarly. Gases have widely spaced individual particles.

Here, P and T are the pressure and temperature of an enclosed ideal gas and k is a constant of proportionality. Gay-Lussac's law says the pressure of an enclosed ideal gas is directly proportional to its temperature at the constant volume of the gas. The law is sometimes called pressure law because it relates the pressure of a gas to the temperature of the gas. For a fixed amount of gas at the constant volume, the pressure P is directly proportional to the temperature T. Let P 1 and P 2 be pressures at temperatures T 1 and T 2 respectively. We can establish the relation between the two conditions. From the above formula, we can calculate the pressure or the temperature at any unknown condition if the pressure and the temperature are known at any one condition.

Gay-Lussac's Law Definition
Gay-Lussac's Law states that the pressure of a sample of gas at constant volume, is directly proportional to its temperature in Kelvin. When any three of the four quantities in the equation are known, the fourth can be calculated. For example, we've known P 1 , T 1 and P 2 , the T 2 can be:. The measurement of space taken by a substance, it is length cubed, typical units are L, mL and m3.
Random converter. If you need to use the absolute pressure, just set the atmospheric pressure to zero. To calculate, select the unknown value, enter the other three values and click the Calculate button. Between and , a French physicist and chemist Joseph Louis Gay-Lussac conducted a series of careful experiments with various gases and determined that the pressure of a given mass of an ideal gas is directly proportional to the absolute temperature of the gas if its volume is kept constant. In terms of energy, this law can be explained given temperature is a measure of the average kinetic energy of gas and as this energy increases, the gas particles have more kinetic energy, causing them to hit the walls of the container with more force, which result in greater pressure.
