To set up a demonstration of the heating of gas under adiabatic compression, the procedure involves putting a few scraps of paper into a large gas test tube, which is then sealed off with a piston. if the piston compresses the trapped air very rapidly, the paper will catch fire. if the volume of trapped air is not reduced enough, the demonstration won't work. estimate the factor by which the volume of air trapped by the piston must be reduced for this demonstration to work. why will the paper not catch fire if the piston is depressed slowly? note that, to make this estimate, you'll need to look up values and can make assumptions including, for example, that the burning point of paper is 233 c
