1. Kinetic Theory

   • The internal energy of a gas is equal to the sum of both the translational and rotational energy of the gas molecules
   • There are two different forms of gases: monoatomic and diatomic
     • Monoatomic gases consider movement in all directions
     • Diatomic gases consider movement in all directions butnalso consider rotational movement

2. 1st Law of Thermodynamics

   • The change in internal energy of a gas is equal to the heat contained within the gad minusnthe work done by the gas
     • Energy is conserved in this process

3. 2nd Law of Thermodynamics

   • Heat is always spontaeously flowing from a warm body to a colder one
   • Heat to a system depends on the path the gas molecules take
   • Internal energy of a system is not dependent on the path the gas molecules take

4. Properties of Work

   • Isobaric Process is a constant pressure process
   • Isothermic Process is a constant temperature process
   • Isochoric Process is a constant volume process

5. Pressure-Volume Diagrams

   • Important because they visually display the relationship between pressure, volume, and work
