A piston is filled with gas. When the pressure is increasing, what is happening to the volume? Assume that all other properties of the gas remain constant.
a. It is remaining the same.
b. It is increasing.
c. It is decreasing.
d. It is increasing or decreasing until it reaches zero.
The correct answer is letter C. Volume is decreasing. For a fixed amount of an ideal gas kept at a fixed temperature, pressure and volume are inversely proportional.
