Chapt. 21Thermodynamics III: Second Law and Entropy169021 qmult 00500 1 1 4 easy memory: state function12. If you integrate a change in a quantity around any closed path on ap-Vdiagram, and the resultis always zero, this suggests that the quantity is:a) heat.b) work.c) a state fair.d) a state function.e) a mare’s-nest.021 qmult 00510 1 1 1 easy memory: entropy definedExtra keywords:physci13. The thermodynamic quantity that is a measure of microscopic disorder is:a) entropy.b) temperature.c) pressure.d) density.e) volume.021 qmult 00520 1 4 3 easy deducto-memory: entropy law emergent principleExtra keywords:physci14. The 2nd law of thermodynamics (which the instructor at least calls the entropy law) say that theentropy of a closed, macroscopic system will increase until it reaches a maximum at which pointthe system will be in thermodynamic equilibrium and will be unchanging at the macroscopiclevel.Entropy in thermodynamics is a well-defined measure of microscopic disorder.The
