A monoatomic gas at pressure P_(1) and volume V_(1) is compressed adiabatically to 1/8th of its original volume. What is the final pressure of gas.

A cylinder with a movable piston contains 3 moles of hydrogen at standard temperature and pressure. The walls of the cylinder are made of a heat insulator and the piston is insulated with a pile of sand kept on it. By what factor does the pressure of the gas increase if the gas is compressed to half its original volume?
