## Using footnotes

The Eckerd Wiki now has footnote capabilities!

From the Wikimedia page: http://meta.wikimedia.org/wiki/Help:Footnotes

## Formulas $v=\lim _{{\Delta t\to 0}}{\frac {\Delta x}{\Delta t}}\quad a=\lim _{{\Delta t\to 0}}{\frac {\Delta v}{\Delta t}}$ $Range={\frac {v_{0}^{2}\sin \theta _{0}}{g}}$ $x={\frac {-b\pm {\sqrt {b^{2}-4ac}}}{2a}}$

Constant Acceleration Formulas $x_{f}=x_{0}+v_{0}t+{\frac {1}{2}}at^{2}$ $v_{f}=v_{0}+at$ $v_{f}^{2}=v_{0}^{2}+2a\Delta x$ ${\bar v}={\frac {v_{f}+v_{0}}{2}}$

## Extensions

Extensions are additions beyond the standard MediaWiki capabilities. Feel free to recommend extensions to Steve Weppner.

We have a poem extension for easy free verse formatting.

A better discussion extension has been added which adds the signature automatically. This is automatically used on all discussion pages.

We also have reference, Java, and Flash extensions (YouTube). For a complete list of extensions see Special:Version.

For chemistry we have recently added a neat Jmol extension.

Here is the Google Extension tested

Here is the testing pdf extension tested

## Converting to Wiki

There is a nice program to convert your webpage to Wiki format located here. To use it you must cut and paste your webpage source (html) into the box and then press the convert button. If your webpage has any pictures you must upload those pictures (using the same filename that the webpage uses) manually to the Wiki. This process has only been tested on simple webpages.--Weppnesp 08:31, 14 November 2007 (EST)

The Open Office word processor program (starting with version 2.4) exports to MediaWiki format. The Eckerd College Campus endorses the use of Open Office, contact ITS to get it installed on your computer. The webpage is here.

## The First Law of Thermodynamics

Ideal Monatomic gas:

The work done by a gas when its volume increases by: dV=Adl is dW=PdV $\Delta$E=3/2 nR $\Delta$T

Special Processes in Carnot Engine Cycle: Contains 2 Isothermal Processes and 2 Adiabatic Processes

Ql/Tl=Ql\Th

• Simple Thermodynamic Processes and the First Law*

1.Isothermal (2): Gas is held at a constant Temperature T=constant $\Delta$T=0 makes $\Delta$E=0, so, Q=W

2.Adiabatic (2): No heat flows into or out of the gas Q=0, $\Delta$E=-W

3. Isobaric: Gas is held at a constant pressure P=constant, Q= $\Delta$E+W = $\Delta$E + P $\Delta$V

• Molar Specific Heats for Gases*

Volume Constant: Q=nCv $\Delta$T

Pressure Constant: Q=nCp $\Delta$T

Cv=Mcv Cp=Mcp

(M= m/n in grams/mol)

4. Isovolumetric V=Constant, $\Delta$V=0 makes W=0, so Q= $\Delta$E

## Entropy

Entropy can be interpreted as a measure of the order or disorder of a system $\Delta$S=Q/T (If temperature is constant)

dS=dQ/T (If temperature is not constant)

T= is in kelvin

## Efficiency

Carnot Efficiency: e=W/Qh, =Qh-Ql/Qh, 1-Ql/Qh

Kelvin Temperatures for Carnot Cycle: e(ideal)=1-Tl/Th

Isothermal Process for a-b:

Wab=nRTh ln Vb/Va
