Gay lussac law of combining volume
Gay-Lussac’s law or Amonton’s law states that the absolute temperature and pressure of an ideal gas are directly proportional, under conditions of constant mass and volume. In other words, heating a gas in a sealed container causes its pressure to increase, while cooling a gas lowers its pressure. The reason this happens is that increasing temperature imparts thermal kinetic energy to gas molecules. As the temperature increases, molecules collide more often with the container walls. The increased collisions are seen as increased pressure.
The law is named for French chemist and physicist Joseph Gay-Lussac. Gay-Lussac formulated the regulation in 1802, but it was a formal statement of the relationship between temperature and pressure described by French physicist Guillaume Amonton in the sdelayed 1600’s.
Gay-Lussac’s law states the temperature and pressure of an ideal gas are directly proportional, assuming constant mass and volume.
Gay-Lussac’s Law Formula
Here are the three common formulas for Gay-Lussac’s law:
P ∝ T
(P1/T1) = (P2/T2)
P1T2 = P2T1
P stands for pressure, while T is absolute temperature. Be sure to c

Combination by Volume: Gay-Lussac
The French scientist Louis-Joseph Gay-Lussac (1778-1850; also known as Joseph-Louis Gay-Lussac, but Louis-Joseph is the preferred name at the French National Library; view portrait at the Wellcome collection) made important contributions concerning the physical and chemical properties of gases. Besides the work described in this selection, he helped found that the volume of a gas at constant pressure varies simply with its temperature [Gay-Lussac 1802], a finding known today as Charles' law. His study of gases was not confined to the laboratory: he ascended several thousand meters in a baloon to make meteorological and magnetic measurements, and to collect samples of gas for chemical analysis (as depicted in this illustration at the Science History Institute). Outside his review of gases, Gay-Lussac was first to isolate the element boron. His serve on the acids hydrogen fluoride, hydrogen chloride, hydrogen iodide, and hydrogen cyanide led to the realization that acids need not include oxygen. He was known as a careful experimenter, particularly in developing analytical techniques involving measurements of volume State Gay-Lussac's law of combining volumes of gases? Give an example.

Question: State Gay-Lussac's law of combining volumes of gases and provide an example to illustrate its application. Answer: Gay-Lussac's law of combining volumes of gases states that when gases react together to shape other gases, and all volume measurements are made at the same temperature and pressure, the volumes of the reacting gases and the volumes of the products (if gases) are in simple whole number ratios. An example can be the reaction between hydrogen gas (H2) and oxygen gas (O2) to shape water vapor (H2O): 2 H2(g) + O2(g) -> 2 H2O(g) Here, the volume ratios are H2:O2:H2O = 2:1:2. If we have 4 L of hydrogen gas and 2 L of oxygen gas for the reaction, both measured at the alike temperature and pressure, the reaction will produce 8 L of water vapor according to Gay-Lussac's law.

Gay Lussac’s Law of Combining Volumes
Gay Lussac’s Law of Combining Volumes states that when gases react, they do so in volumes which bear a simple ratio to one another, and to the volume of the product(s) formed if gaseous, provided the temperature and pressure remain constant.
The commandment explains experimental facts about how gaseous atoms combine. Example:
For the reactions:
(i) N2(g) + 3H2(g) → 2NH3(g)
1 vol. 3 vols. 2 vols.
1 volume of nitrogen combines with 3 volumes of hydrogen to form 2 volumes of ammonia.
(ii) 2H2(g) + O2(g) → 2H2O(g)
2 vols. 1 vol. 2 vols.
2 volumes of hydrogen combine with 1 volume of oxygen to form 2 volumes of steam.
