The pressure exerted by a gas on the container in which it is held varies inversely with the volume of the container. A pressure of 50 pounds per square inch is exerted on a container of volume 4 cubic feet. What is the pressure on a container whose volume is 10 cubic feet?
A) The pressure is 20 pounds per square inch.
B) The pressure is 500 pounds per square inch.
C) The pressure is 125 pounds per square inch.
D) The pressure is 40 pounds per square inch.
E) The pressure is 200 pounds per square inch.

The pressure-volume relationship is described by Boyle's Law, which states that pressure is inversely proportional to volume when temperature and amount of gas are constant. Therefore, if the volume increases from 4 to 10 cubic feet, the pressure decreases in inverse proportion: $50 \times \frac{4}{10} = 20$ pounds per square inch.
