Thermodynamics Laws and Processes

Study Notes

Thermodynamics Laws

First Law of Thermodynamics: Energy cannot be created or destroyed, only transformed from one form to another.
Joule-Thomson Coefficient: Measures the change in temperature of a gas or liquid when it expands through a porous plug or valve at constant enthalpy.
Entropy: A thermodynamic property that measures the degree of disorder or randomness in a system. It represents the total amount of energy in a system that is unavailable to do useful work.
Enthalpy: A thermodynamic property that represents the total energy content of a system. It includes the internal energy of the system plus the energy associated with the pressure and volume of the system.

Thermodynamic Processes

Maxwell's Thermodynamic Relations: Mathematical equations derived using the fundamental equations of thermodynamics, which relate the partial derivatives of thermodynamic variables such as temperature, pressure, volume, and entropy.
Adiabatic Process: A process that occurs without any heat transfer between the system and its surroundings. In an adiabatic process, entropy remains constant because no heat is added or removed from the system.
Internal Energy as a State Function: Internal energy is a state function, meaning its value depends only on the current state of the system and not on how the system got there.
Joule-Thomson Porous Plug Experiment: Demonstrates the Joule-Thomson effect, where gas expands through a porous plug, resulting in a change in temperature. The experiment is used to determine the Joule-Thomson coefficient of a gas.
