Review:
Archimedes' Principle: the weight of displaced water (or fluid) is equal to (but opposite to) the buoyant force.
Bernoulli's Principle: in a narrowing pipe pressure decreases and velocity increases.

23. ρ = m/v

24. P = P0 + ρgh

Important Equations:

18. Heat = Change in Energy + Work

19. Temperature in Ferinheight = 9/5 Temperature in Celsius + 32
20. Temperature in Kelvin = Temperature Celsius + 273

21. Pressure x Volume = Number of Moles x Gas Constant x Temperature  
      Gas Constant = 8.314 J/kmol or 0.082 Latm/kmol

22. Specific Heat of Water = 1 calorie/g°C \
      [1 calorie = 4.186 J/g°C]

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. TF = 9/5 TC + 32
20. TK = TC + 273

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

22. cH2O = 1 calorie/g°C [1 calorie = 4.186 J/g°C]

Important Equations:

4. Torque = Force in Direction of Motion x Distance ; Torque = Distance x Force x Sinθ

5. Force = Mass x Acceleration

6. During Translational Equilibrium the Sum of Forces = 0
7. During Rotational Equilibrium the Sum of Torques = 0

8. Force of Gravity = (Universal Constant of Gravitation x Both Masses) /Distance Between Masses2 
*The Universal Constant of Gravitation (G) = 6.67x10-11N(m/kg)2

My Notes Work and Energy (Before Quiz)


Important Equations:

12. Work = Force Parallel to Motion x Distance Moved

13. Kinetic Energy  = 1/2 Mass x Velocity2
14. Work = 1/2 Mass x Initial Velocity- 1/2 Mass x Final Velocity2

15. Potential Energy = Mass x Gravity x Height

16. Total Energy = Initial Kinetic Energy + Initial Potential Energy 
      Total Energy = Final Kinetic Energy + Final Potential Energy

17. Power = Change in Work/ Change in Time
