Question
This quantity times RT over M equals the square of the speed of sound in an ideal gas. For 10 points each:
[10e] Name this quantity symbolized gamma. This quantity equals the ratio of heat capacities at constant pressure and constant volume.
ANSWER: adiabatic index [accept specific heat ratio; accept Laplace's coefficient; accept isentropic expansion factor; prompt on heat capacity ratio]
[10h] The difference in heat capacities at constant pressure and constant volume equals molar volume times temperature times alpha-squared divided by this quantity. At constant particle number and temperature, this quantity is proportional to the average fluctuation of volume, all over volume.
ANSWER: isothermal compressibility [or isothermal coefficient of compressibility; accept beta-sub-T; prompt on coefficient of compressibility; prompt on beta; reject “compressibility factor”; reject “compression factor”]
[10m] When the ideal gas law applies, an adiabatic process can be viewed as one of these processes with an exponent equal to the adiabatic index. In general, pressure times volume to the n is constant in these processes.
ANSWER: polytropic processes [accept polytropic index]
