MCAT Learning Materials: Lesson 5 Thermodynamics

Let's Begin Thermodynamics:

Review:

1st Law of Thermodynamics (Conservation of Energy): Energy is neither created nor destroyed. See Eq. 18.

2nd Law of Thermodynamics: In a closed system entropy (disorder) always increases.

18. Q = U₁ - U₂ + W

19. T_F = 9/5 T_C + 32
20. T_K = T_C + 273

21. PV = nrt [r = 8.314 J/kmol or 0.082 Latm/kmol]

22. c_H2O = 1 calorie/g°C [1 calorie = 4.186 J/g°C]
