Entropy Flashcards
1
Q
What is the third law of thermodynamics?
A
the entropy of a system approaches a constant value as its temperature approaches absolute zero
2
Q
What is entropy
A
chaos
3
Q
what happens at absolute zero to macro/microstates?
A
at absolute zero, all substances have one microstate
4
Q
more microstates =
A
more entropy
5
Q
how to increase entropy
A
- increase the number of microstates:
to do that:
- increase temp
- increase moving space
- increase mixing
6
Q
Gibbs Free Energy Equation
A
ΔG = ΔH– TΔS
G = chane in free energy
H = enthalply
T = temp
S = entropy?
7
Q
gibbs equation -> positive
A
nonspontaneous
8
Q
gibbs equation -> negative
A
spontaneous
9
Q
What is heat
A
Energy + (pressure*volume)
