Formulas and Key Relations
Types of Thermodynamic Processes
Isothermal Process
Temperature constant (ΔT = 0, ΔU = 0 for ideal gas)
Isobaric Process
Pressure constant (ΔP = 0, occurs at atmospheric pressure)
Isochoric Process
Volume constant (ΔV = 0, reactions in closed containers)
Internal Energy and First Law of Thermodynamics
Mathematical form
ΔU = Q + W
Key relations
For reactions at constant pressure, ΔH = Qp (heat absorbed at constant pressure).
A measure of molecular disorder or randomness in a system. ΔS = Qrev/T for reversible processes.
