Determining γ for air all bullets must be addressed in your lab write-up, and a random subset will be graded. design an experiment to determine the constant (the ratio of the heat capacity at constant pressure to the heat capacity at constant volume), for air. you have an air-filled two-liter bottle at a pressure in the range 135-145kpa (ask your ta for if it is too low), a pressure sensor linked to a computer (the file is "2 liter bottle"), and a lever by which you can compress the bottle. you should start with a quick compression, then decide whether, to provide enough information to calculate what you seek, this process should be followed (immediately) by another one. note: it would probably be a very good idea to review in your text the concept of an "adiabatic process" before proceeding with your experiment.
