Study Notes
Thermodynamic Processes
- An isothermal process is characterized by a constant temperature.
- A constant pressure process is known as an isobaric process.
- A key feature of a quasi-static process is that it occurs slowly enough for the system to remain in internal thermal equilibrium.
Adiabatic Processes
- In an adiabatic process, there is no heat flow into or out of the system.
Quasi-Static Processes
- A quasi-static process is a slow process that allows the system to remain in internal thermal equilibrium.
- What differentiates a quasi-static process from other processes is that it is reversible, meaning it can be reversed by an infinitesimal change in the environment.
- The main characteristic of a quasi-static process is that it occurs slowly enough for the system to remain in internal thermal equilibrium.
Isothermal Processes
- The condition PV = constant in an isothermal process represents the ideal gas law.
- The equation PV = nRT is used to represent the pressure of an ideal gas in an isothermal process.
Idealized Quasi-Static Processes
- The idealized quasi-static process is characterized by a continuous series of equilibrium states.
Non-Equilibrium States
- Non-quasi-static processes are difficult to deal with due to frequent non-equilibrium states.
State Variables
- Q (heat) is not considered a state variable in thermodynamics.
