Who reconciled Dalton's atomic hypothesis with Gay-Lussac's results on the combination of volumes in 1811?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. Amadeo Avogadro.
In 1811, Amedeo Avogadro reconciled Dalton’s atomic hypothesis with Gay-Lussac’s results on gas volume combinations.
He proposed that equal volumes of gases at the same temperature and pressure contain the same number of molecules, explaining why gases combine in simple ratios.
This resolved the conflict between Dalton’s indivisible atoms and Gay-Lussac’s volume ratios, laying the foundation for modern atomic theory. Avogadro’s hypothesis was later validated, becoming a cornerstone of chemistry.
