Start reading chapter 1

Questions about Heating Cooling curve Excel?

Sec 1.2: Basic Definitions

- Systems and Surroundings
DEMO: box of system types
  • open/closed...exchange of matter or not
  • adiabatic/diathermal...heat loss or not
  • walls...rigid or moveable/permeable/impermeable
  • system variables...for a gas, pressure (P), temperature (T), volume (V), amount (n)
  • equation of state...for a gas, ideal gas law

We mainly study gases while developing the basic aspects of thermodynamics

  • 0th Law of Thermodynamics: thermometers work!
- Internal Combustion Engine Example Calculation ([[Media:Combustion_ex_02.pdf|worksheet])

Sec 1.3: Thermometry (covered in lab)
