Day 5 Heat Engines and Cycles

First we had the Candle experiment. We had to predict what would happen to the flame.

The flame would suffocate by the CO2

We then had to explain the Chimney effect.

Our reasoning.

We said that it would get dimmer.

A video demonstration by Prof. Mason.

Setting up experiment.

The Chimney experiment running.

The light will eventually go out in part by the CO2 and water vapor being unable to escape.

The PV diagrams. Isobaric, Isochoric, Adiabatic, and Isothermal. Distinguishing between isothermal and Adiabatic is difficult.

Graphs for the different types of process.



Active physics problems worked out.

Active physics problmes worked out.



Our steps for a simple factory. Used heat engine.



White board work of the water tank problem.

Water Tank problem, we used mgh and pv-nrt and to the final answer of 2e^7 J.




White board work of an entire Heat engine cycle.

Video of Tommy showing off a Carnot Engine.

Summary:

Fist we did a Candle experiment and explain why it would go out.

Then we talked about the Chimney effect and saw a demonstration of it.

We then worked out problems on Active Physics to find properties of the different process in a Heat Engine.

Then we did a Heat Engine example, and a water tank example. And finished class with a Carnot demonstration.
