Charle's Law was given by Jacques Charles in_______?
Correct answer: B. 1787
- A. 1785
- B. 1787
- C. 1880
- D. 1885
Explanation
Jacques Charles studied the relationship between gas volume and temperature around 1787, although the law was later published and quantified by Gay-Lussac. The dates 1880 and 1885 are much too late, while 1785 is not the standard date, making 1787 correct.

About Charles's Law
At constant pressure, the volume of a fixed mass of gas is directly proportional to its absolute temperature. Questions involve the Kelvin scale, the equation V₁/T₁ = V₂/T₂, volume-temperature graphs, and the need to distinguish Charles's law from Boyle's law, which relates pressure and volume.
