Who described in 1662 that when a gas was pumped into an enclosed space, it would shrink to fit in that space, but the pressure exerted by the gas on the container would increase?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. Robert Boyle.
The description you're referring to is associated with Robert Boyle, who in 1662 formulated what is now known as Boyle's Law. Boyle's Law states that the pressure of a gas is inversely proportional to its volume when temperature is held constant.
Boyle conducted experiments that showed when a gas is compressed (its volume decreases), the pressure exerted by the gas increases proportionally. This observation laid the foundation for understanding the relationship between the volume and pressure of gases, which is a fundamental principle in the field of gas laws.
