In 1662, who described the equation P1V1 = P2V2, where P1 and V1 are the initial pressure and volume values, and P2 and V2 are the pressure and volume values of the gas after the transformation?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. Robert Boyle.
The Anglo-Irish scientist Robert Boyle described the equation P₁V₁ = P₂V₂ in 1662, establishing what is now called Boyle’s Law. This law states that at constant temperature, the pressure of a gas is inversely proportional to its volume. Boyle’s experimental work with air and mercury columns gave birth to this quantitative relationship, making it one of the earliest gas laws. His work marked a significant advancement in the field of physics and chemistry and helped in the foundation of modern thermodynamics.
Other Options:
-
Joseph Gay-Lussac – Known for Gay-Lussac’s Law related to pressure and temperature.
-
Amedeo Avogadro – Proposed Avogadro’s Law in 1811, relating volume and number of gas particles.
-
John Dalton – Known for Dalton’s Atomic Theory.
