- ‘This law provides an explanation for why Gay-Lussac's law of combining volumes works.’
- ‘Charles' law also is known as Gay-Lussac's law and the constant pressure law.’
- ‘If this was the right formula for water, then both Gay-Lussac's law of combining volumes and Lavoisier's law of conservation of mass could not be right.’
