Question

On the basis of his experiments, Robert Boyle reached the conclusion that at constant temperature, the pressure of a fixed amount(number of moles,`n`) of gas varies…….
A. directly
B. inversely
C. abruptly
D. smoothy

Answer 1

Correct Answer - B
The first set of quantitative measurements on the gaseous state were made by Robert Boyle. He devised a very simple apparatus to study the relation between the pressure and volume of a gas. Using a bent (J-shaped) tube and some liquid metal mercury , Boyle found that the length of the trapped air ( to which the volume of the air was directly proportional) varies inversely with the pressure applied to it. Boyle performed the experiment in a room where the temperature was approximately constant and he only needed a bent tube, some mercury , and a measuring scale for his experiment. Boyle worked only with air, but when other gases were discovered , it was found that they also showed the same relationship between volume and pressure at constant temperature.
