Third Law of Thermodynamics Flashcards
1
Q
What is the third law of thermodynamics?
A
The entropy of all perfect crystalline substances at T = 0 is 0
2
Q
What is a microstate?
A
Energy state
3
Q
Equation for Helmholtz
A
A = U - TS
if A = negative then it is spontaneous
4
Q
Equation for Gibbs Free Energy
A
G = H - TS
If G = negative then it is spontaneous
5
Q

A
delta A at constant T,V is greater than or equal to 0
delta G at constant T,P is greater than or equal to 0
