Ideal Gases Flashcards
1
Q
entropy (S)
A
Measure of usefulness of a particular quantity of energy. Low entropy means more useful.
= Q / T
*temperature (T)
*heat (Q)
2
Q
can entropy be reversed
A
no entropy can’t be reduced, was lost it can not be recovered
3
Q
isobaric process
A
p = constant, n = 0
4
Q
isothermal process
A
T = constant, n = 1
5
Q
isometric process
A
V = constant, n = infinity
6
Q
adiabatic process
A
ΔQ = 0, n = γ
7
Q
polytropic processes
A
a process that obeys the relation, PV^n = constant
*isobaric, P = constant
*isothermal, V = constant
*isometric, T = constant
*adiabatic, Q = constant
8
Q
what is γ for air
A
1.4
9
Q
system is positive
A
Q tranfer to system W on system
