#1

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 by having a pile of sand on it. By what factor, does the pressure of the gas increase if the gas is compressed to half its original volume?


#2

As no heat is allowed to be exchanged, the process is adiabatic.
