cycle

A

a series of processes that result in the final state being identical to the initial state

17
Q

A

all the states the system passes through may be considered as equilibrium states

18

quasi-static

A

same as quasi-equilibrium

19

mass per unit volume

26
Q

pressure

A

normal force on a defined area

27
Q

temperature

A

not possible to define

28
Q

thermal equilibrium

A

no state change due to temperature difference

29
Q

mechanical equilibrium

A

no state change due to pressure differences

30
Q

thermodynamic equilibrium

A

no state change due to any thermodynamic property

31
Q

zeroth law

A

when two bodies are in thermal equilibrium with a third body, they are in equilibrium with each other

32
Q

first law

A

energy is conserved (change in energy of system + change in energy of surroundings = 0)

33
Q

second law

A

entropy increases (change in entropy of system + change in entropy of surroundings >0)

34
Q

third law

A

the absolute entropy of a pure crystalline structure in complete internal equilibrium is zero at zero degrees absolute
