what is the law about?
The pressure of a given mass of gas varies directly with the absolute temperature of the gas, when the volume is kept constant.
Gay-Lussac's law
Gay-Lussac's law (more correctly referred to as Amontons's law) states that the pressure of a given mass of gas varies directly with the absolute temperature of the gas, when the volume is kept constant.
what does the column in the periodic table mean The columns, called groups, contain elements with similar chemical behaviours. what is this tabular structure used for? To classify chemical elements which are arranged by atomic number, electron configuration, and recurring chemical properties. The structure of the table shows periodic trends. does this contain only metals? No, it also contains metalloids, nonmetals and noble gases. where are the first one placed in the table? Somewhere between metals and nonmetals what are the different types of the former substance mentioned by you? Boron, silicon, germanium, arsenic, antimony and that of the latter? hydrogen, helium, nitrogen, oxygen,  fluorine, neon by whom was this table first developed? Dmitri Mendeleev who was he? A Russian chemist and inventor. where was he born? Verkhnie Aremzyani, Siberia can you name any institution that he attended either as a student or a faculty? UNANSWERABLE who were his parents? Ivan Pavlovich Mendeleev, Maria Dmitrievna Mendeleeva when did he develop the table? 1869 what other things is he famous for? He researched in the fields of hydrodynamics, meteorology, geology, certain branches of chemical technology can you mention any particular achievement ? He investigated the expansion of liquids with heat, and devised a formula similar to Gay-Lussac's law of the uniformity of the expansion of gases was this particular law named after any person? Yes

Gay-Lussac's law [SEP] Introduction
Gay-Lussac's law (more correctly referred to as Amontons's law) states that the pressure of a given mass of gas varies directly with the absolute temperature of the gas, when the volume is kept constant. Mathematically, it can be written as: formula_1. Gay-Lussac is incorrectly recognized for the Pressure Law which established that the pressure of an enclosed gas is directly proportional to its temperature and which he was the first to formulate (c. 1809). He is also sometimes credited with being the first to publish convincing evidence that shows the relationship between the pressure and temperature of a fixed mass of gas kept at a constant volume.
