1) The amount of energy should be the same even though the order of processes is different. Assuming the same efficiency of work to heat and heat to work, then it would have to be the same net work created.

2) A Carnot cycle differs from our 4 step process in that the order is isothermal expansion, adiabatic expansion, isothermal compression, and then adiabatic compression. This allows for 100% conversion of heat to work AND vice versa. The sign chart looks like this-

Step	Process	Q	W	$\Delta U$
1	isothermal expansion	+	-	0
2	adiabatic expansion	0	-	-
3	isothermal compression	-	+	0
4	adiabatic compression	0	+	+

The difference in signs are due to the adiabatic processes that occur.

Using an ePortfolio

Introduction
ePortfolios are a place to demonstrate your work. They are made of sections and pages. The list of sections are along the left side of the window (show me). Each section can have multiple pages, shown on the right side of the window (show me).
Portfolio Sections

Sections are listed along the left side of the window (show me). Each section can have multiple pages inside of it. To organize or add sections, click the "Organize Sections" link (show me).

You can rename any section by clicking on the icon that appears, rearrange sections by clicking and dragging them, or delete sections by clicking the icon.
Section Pages

Sections have multiple pages. You can see the list of pages for the current section on the right side of the window (show me). To organize or add pages, click the "Organize/Manage Pages" link (show me).

You can rename any page by click on the icon that appears, delete a page by clicking the × icon, or rearrange the order of pages by click and dragging them.
Page Content
The content you see on a page is the same content any visitors will see. To edit this content, click the " Edit This Page" link (show me) and the page will change to editing mode.

Now you're editing! Rename the page or change commenting options (show me) if you like. You can save, preview or cancel your changes at any time by clicking the button on the right side (show me).

Content is divided into subsections, which each have a dotted border. You can delete or edit the contents of a subsection by clicking the or icons at the top right corner of the subsection.

To add new subsections, find and click the type of content you want to add in the options list on the right side of the page (show me).
ePortfolio Settings
To change the settings for your ePortfolio, click the "ePortfolio Settings" link (show me). You can rename the portfolio and also change whether it is public or private. Private portfolios are only visible to those to whom you grant access.
