1. Introduction
Quantity of the ratio of heat capacity at constant pressure Cp to heat capacity at constant volume Cv for gases plays a major role at the adiabatic processes and at processes of the close to them. For an example a sound velocity in gases, a flow of gases on pipes with sound velocities and achievement of hyperacoustic velocities in dilating pipes are defined by this ratio.
2. Background Knowledge
Soundwaves are propagated through air and other gases as a series of compressions and expansions; these variations in the transmission medium take place so rapidly that there is no time for energy to

In general, the air is composed with 78% Nitrogen, 21% Oxygen, 0.3% Carbondioxide, and etcedra. In Table 6.1, Cv, Cp, and γ of this molecules are similar with our measured data. Beacuase of this, I am sure that our experience was almost correct, and the data is very good one.
By the way, why there was error in the result? Well, we can see there is larger standard deviation as the volume of squirt gun increase. If the volume increase, it needs more time to shrink the piston. Then the heat will move through inside or outside of vessel, the process is not adiabatic any longer. Therefore the error is bigger as volume increase.
Then what is the significance of the ratio γ? I think it represents the character of gas. In Table 6.1, various kinds
