Thermodynamics

1. Heat

• heat
• thermal equilibrium
• thermal energy
• conduction
• convection
• Heat (\(Q\)) measured in J

2. Temperature

• kelvin
• absolute temperature scale
• Temperature (\(T\)) measured in K
• When a physics equation contains a \(T\), use Kelvin.
  When a physics equation contains a \(\Delta T\), you may use either Kelvin or Celsius.

3. Heat Capacity

• heat capacity
• specific heat
• thermal reservoir
• thermal energy
• heat capacity (\(C\)) measured in J/K
• specific heat (\(c\)) measured in J/kg/K
• Thermal Energy (\(E_{th}\)) measured in J
• \(C=mc\)
• \(E_{th}=CT=mcT\)

4. Phase Changes

• melting (or freezing) temperature
• boiling temperature
• sublimation temperature
• latent energy
• latent heat
• Latent Energy (\(E_L\)) measured in J
• Latent Energy per kg (\(L\)) measured in J/kg
• \(E_L=mL\)

5. First Law of Thermodynamics

• first law of thermodynamics
• Heat (\(Q\)) measured in J
• \(\Delta E=W+Q\)

6. Perpetual Motion

• perpetual motion machines
• heat engines
• second law of thermodynamics
• perpetual motion machines of the second kind

7. Heat Engines

• heat engine
• efficiency
• Efficiency (\(\eta\)) no units
• \(Q_{in}=W_{out}+Q_{out}\)
• \(\eta={W_{out}\over Q_{in}}\)

8. Carnot Engines

• carnot engine
• \(\eta\le {T_H-T_C\over T_H}\)

9. Other Engines

10. Entropy

• entropy
• second law of thermodynamics
• closed system
• Entropy (\(S\)) measured in J/K
• The entropy of a closed system will never decrease.

11. Entropy and Heat

• \(\Delta S=+{Q\over T}\)

12. Heat Pumps

• heat pumps
• refrigerators
• coefficient of performance
• Coefficient of Performance (\(COP\)) no units
• \(COP={Q_C\over W_{in}}\hbox{ for cooling}\)
