Use Direct and Inverse Variation · Exercise 28
Write an inverse variation equation to solve the following problems.
The volume of a gas in a container varies inversely as pressure on the gas. A container of helium has a volume of 370 cubic inches under a pressure of 15 psi.
ⓐ Write the equation that relates the volume to the pressure.
ⓑ What would be the volume of this gas if the pressure was increased to 20 psi?
Its source prints no answer for this problem, so there's nothing to check against.
