The 3 Laws of Thermodynamics
0th Law: If system A is in thermal equilibrium with system B, and system B is in thermal equillibrium with system C, then system A is in thermal equillibrium with system C also.
1st Law: If work is performed on/by a system (±ΔW), and/or heat is added to or extracted from the system (±ΔQ), then the change in the system's internal energy is given by ΔU = ΔW + ΔQ.
2nd Law: A system will always tend to a state of higher disorder. (Concept of entropy)
Equations of state
Ideal Gas: The molecules in an ideal gas do not interact and are point-like in size/shape.
Van der Waals Gas: The molecules in a Van der Waals gas do interact and have finite shape/size.
