Question

joseph louis gay - lussac (1778 - 1850) grew up during both the french and chemical revolutions. his comfortable existence as the privately tutored son of a well - to - do lawyer was disrupted by political and social upheavals: his tutor fled, and his father was imprisoned. joseph, however, benefited from the new order when he was selected to attend the école polytechnique, an institution of the revolution designed to create scientific and technical leadership, especially for the military. there his mentors included pierre simon de laplace and claude louis berthollet, among other scientists converted by antoine - laurent lavoisier to oxygen chemistry. gay - lussac’s own career as a professor of physics and chemistry began at the école polytechnique. he shared the interest of lavoisier and others in the quantitative study of the properties of gases. from his first major program of research in 1801 - 1802, he concluded that equal volumes of all gases expand equally with the same increase temperature: this conclusion is usually called “charles’s law” in honor of jacques charles, who had arrived at nearly the same conclusion fifteen years earlier but had not published it. in 1804 gay - lussac made several daring ascents of over seven thousand meters above sea level in hydrogen - filled balloons—a feat not equalled for another fifty years—that allowed him to investigate other aspects of gases. not only did he gather magnetic measurements at various altitudes, but he also took pressure, temperature, and humidity measurements and samples of air, which he later analyzed chemically. in 1808 gay - lussac announced what was probably his single greatest achievement: from his own and others’ experiments he deduced that gases at constant temperature and pressure combine in very simple numerical proportions by volume, resulting in a product or products—if gases—also bear a simple proportion by volume to the volumes of the reactants. fill in the blank. 1. from his first major program of research, he concluded what? 2. gay - lussac’s conclusion in his first major program research is known as

Explanation:

1. The text states "From his first major program of research in 1801 - 1802, he concluded that equal volumes of all gases expand equally with the same increase temperature".
2. It also mentions "This conclusion is usually called 'Charles's law' in honor of Jacques Charles, who had arrived at nearly the same conclusion fifteen years earlier but had not published it".

Answer:

1. Equal volumes of all gases expand equally with the same increase in temperature.
2. Charles's law
