For the MCAT exam, you should have a solid understanding of thermochemistry concepts, including:
1. *Laws of Thermodynamics*:
Zeroth Law: Temperature equilibrium
First Law: Energy conservation (ΔE = Q - W)
Second Law: Entropy increase (ΔS = ΔQ / T)
Third Law: Absolute zero and entropy
2. *Thermodynamic Systems*:
Closed systems (no matter or energy exchange)
Open systems (matter and energy exchange)
Isolated systems (no energy or matter exchange)
3. *Thermodynamic Processes*:
Isothermal (constant temperature)
Adiabatic (no heat transfer)
Isobaric (constant pressure)
Isochoric (constant volume)
4. *Energy and Work*:
Internal energy (U)
Enthalpy (H)
Heat capacity (C)
Work (W)
5. *Entropy and Free Energy*:
Entropy (S)
Gibbs free energy (G)
Helmholtz free energy (A)
6. *Thermochemical Equations*:
Enthalpy change (ΔH)
Entropy change (ΔS)
Gibbs free energy change (ΔG)
7. *Applications of Thermochemistry*:
Phase transitions
Chemical reactions
Biological systems
Make sure you understand the concepts, definitions, and relationships between these terms to excel in the thermochemistry section of the MCAT exam!
