Question 192989
 The volume of a gas is inversley porportional to the pressure on the gas. If the volume is 6 cubic centimeters when the pressure on the gas is 8 kilograms per square centimeter, then what is the volume when the pressure is 12 kilograms per square centimeter?
------------------
V = k/P  (k is some constant)
In this problem:
6 = k/8
k = 48
-----
V = 48/12
V = 4
