Thermodynamics and Kinetics: Part 1

We’re going to dump Achem. The teacher is putting me to sleep. Today’s lecture is the introduction and costs 47 minutes.

Each thermodynamic law defines a quantity. Thermodynamics describes the flow of heat.

Temperature is defined by the 0th law. “The common sense law.”
Energy is defined by the 1st law. U. Energy conservation. “Break even law.”
Entropy is defined by the 2nd law. S. Direction of time. “YOu can break even at Ok.”
Numerical Entropy is the 3rd law. “You can’t win law.”

Thermo is a very mature science. You must define your system well. There is the system, the boundary, and the surroundings.

The open system allows mass and energy in. Closed systems allow energy in but no mass. Isolated systems do not allow mass or energy in.

The first step is defining your system. P,T,V, n and mass are the basic variables. They are macroscopic properties. Homogenious or heterogenious. Number of components and phases.

Extensive properties scale with properties of the system – V, mass. Intensive properties include T, V’ = V/n. State variables for a one component systems, we only need the n + 2 variables.

3 H2 (n, 1 bar, 100 degrees C)

Path is the intermediate steps from initial state to final.
4H2 (g, .5bar, 100c) = 4H2 (g, 1 bar, 50C)

Adiabatic – no heat exchange. Irreversible or reversible? Isobaric is constant pressure. Isothermal is constant temperature.

THe Zeroth Law – heat flows from a warm body to the cold body. An object in between will have an intermediate temperature. Defines the concept and measurement of temperature.

2 reference points are needed.

Fahrenheit – US and Jamaica.
