Questions about Heating Cooling curve Excel?

- 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

- Internal Combustion Engine Example Calculation (worksheet)

- There is a STATE --> described by STATE VARIABLES --> the relationship between the state variables is the EQUATION OF STATE (variables).

- Equations of state allow us to have predictive powers.

- Why do we fit data to math equations...data reduction...x/y data set of 100 points can be reduced to slope and y-intercept.

- Intensive/Extensive properties

Side conversation: Do you have an equation of state? Myers-Briggs Type Indicator

- Kinetic Molecular Theory of Gases (handout)

- van der Walls equation; and example of a real gas equation of state.

Meet in CSB 378

- Pressure data collection: How many moles can you add to a PVC pipe?
