Answer:
a. The pressure of a fixed amount of gas is inversely proportional to its volume.
Explanation:
At constant temperature, the relationship between pressure (P) and volume (V) illustrated in the plot for a gas gives a straight line from the origin.
This relationship was described by a law stated by Robert Boyle, an English Chemist, in 1662.
Boyle's law states that the pressure of a fixed mass of gas is inversely proportional to the volume, provided the temperature remains constant.
The relationship for Boyle’s Law can be expressed mathematically as follows:
P1V1 = P2V2; where P1 and V1 are the values of the initial pressure and volume, and P2 and V2 are the final values of the pressure and volume of the gas.
