During an experiment, the pressure of a fixed mass of gas increased from 40 pounds per square inch (psi) to 50 psi. Throughout the experiment, the pressure, P psi, and the volume, V cubic inches, of the gas varied in such a way that the value of the product PV was constant.
the volume of the gas when the pressure was 40 psi
1.2times the volume of the gas when the pressure was 50 psi
A.Quantity A is greater.
