The work done by a non-isothermal one of these thermodynamic processes equals the change in the product of pressure and volume divided by one minus their namesake index, denoted n. For 10 points each:
[10h] Name these thermodynamic processes in which pressure times volume to the power of n is constant.
ANSWER: polytropic processes [accept polytropic index]
[10e] The polytropic index of an isobaric process has this value. By definition, the change in pressure during isobaric process equals this number.
ANSWER: zero
[10m] The polytropic index of an isentropic process equals the heat capacity ratio, which is also known as the ”[this property] index.” By definition, isentropic processes are reversible and have this property.
ANSWER: adiabatic [accept adiabatic index or adiabatic processes]
