Thermodynamics and Statistical Mechanics: Essentials Flashcards
What is the zeroth Law of Thermodynamics?
Two systems in thermal equilibrium with a third system must be in thermal equilibrium with one another.
Conversion from Celcius to Kelvin

Heat formula

Stefan-Boltzmann Law

Ideal Gas Equation

Average kinetic energy at a given temperature with fixed degrees of freedom for particles

Heat capacities for an ideal gas at constant pressure and constant volume

Work done by an ideal gas

First Law of Thermodynamics

Adiabatic process
No heat flow in or out of the system
Isochoric process
No change in volume
Isobaric process
No change in pressure
Constant in adiabatic processes

Efficiency of a heat engine

The second law of thermodynamics
No heat engine has perfect efficiency, OR, it is impossible for any process to have as its sole result the transfer of heat from a cooler to a hotter body.
Canonical ensemble
All possible states of a system with the same particle number (N), volume (V), temperature (T)
Definition of beta (used for thermodynamics and statistical mechanics equations)

Discrete states partition function

Probability of being found in state i in a system with discrete states

Entropy definition (Boltzmann)

Non-Boltzmann entropy definition

Monoatomic ideal gas entropy

Thermodynamic definition of gamma

Thermodynamic gamma in terms of degrees of freedom

3rd Law of Thermodynamics
The entropy of a perfect crystal at absolute zero is exactly zero.
