2-Thermodynamics

Here is the slideshow I am using in class: Thermodynamics Slideshow

Textbook: Chapters 9, 12, & 13 

Objectives: 

1st Law of Thermodynamics (conservation):

• Internal Energy:

  • Temperature: 

    • qualitatively explain average K of particles being proportional to T

    • connect statistical distribution of microscopic energy to macroscopic T & thermo processes. 

• Heat Transfer:

  • Thermal Conductivity - design an experiment to test thermal conductivity

  • Describe direction of energy transfer in terms of particle interactions

  • describe conduction, convection and radiation models for transferring energy

  • describe approaching thermal equilibrium in terms of particle interactions and probability

• Work:

  • Ideal Gas Law

2nd Law of Thermodynamics (entropy):

• • Ideal Gas Law

Equations: 

Common Misconceptions:

• A cold body contains no heat.

• There is no limit on the lowest temperature.

• At absolute zero motion of every part of an object stops.

• An object has no mass at absolute zero.

• Sweaters will make you warmer.

• Cold can flow.

• Gases can be compressed to zero volume.

• Heat and temperature are the same thing.

• Heat and cold flow like liquids.

• Pressure is the same as force.

• Skin is a good thermometer.
