Chapter Objectives

After studying this chapter, you should:

• understand the meaning of thermal equilibrium and the role of temperature.
  


• know how to convert between the Celsius, Fahrenheit, and Kelvin temperature scales.
  


• understand the basic phenomenology of thermal expansion.
  


• understand the relationship between heat and work.
  


• understand the difference between specific heat and heat capacity.
  


• be able to perform basic calorimetry calculations.
  


• know the 3 main processes for heat transfer.
  


• understand the basic phenomenology of heat transfer by conduction and radiation.

NOTE:

In order to take advantage of the new features in Java, the Physlets® module uses the the new release of the JDK, JDK 1.1.

Currently, the new version of Java is supported on PCs. running Win95/98/NT.

Note to Mac users: Currently, Physlet® Problems will not run on a Macintosh Power PC since the major browsers for this platform do not support both Java 1.1 and Java to JavaScript communication.

There is an alternative for experienced Mac users, if they are adventuresome. The HotJava browser from Sun Microsystems (http://www.java.sun.com/products/OV_hotjavaProduct.html) freely available is a temporary solution that supports both Java 1.1 and JavaScript to Java communication. Make sure you are using the latest MacOS Runtime for Java (MRJ) available at http://www.apple.com/java/. Send questions to Carl@CarlAdler.org .

In addition, on PCs, the new version of Java works best with the Internet Explorer 4 web browser or higher.

If you are using a PC running Win 95/98/NT and are using Netscape, please download the latest version of Netscape.

The recommended system requirements to use the applets in the Physlets® modules are:

• a Pentium 90 with 16MB RAM
• either Netscape 3.0.3 and higher or Internet Explorer 4.0 or higher. Internet Explorer 3.0/AOL browser does not work!
• Your internet connection should be through your school's local area network. Using a 28.8 modem will result in dramatically increased load times.
