public class Calorimeter

extends edu.davidson.tools.SApplet

implements edu.davidson.tools.SDataSource, edu.davidson.tools.SStepable, java.lang.Runnable

This applet draws a calorimeter (there are three styles available) and simulates a calorimetry experiment.
Style 0 shows no calorimeter (blank applet box)
Style 1 shows a standard calorimeter.
Style 2 shows a thermos-type calorimeter.
Style 3 shows a bomb calorimeter.
Style 4 shows a thermos-type calorimeter with a reservoir that drains into the calorimeter.

Configurable Options include the sample, a heating filament, and a stirrer.

The applet serves as a DataSource (DataConnections) that supplies time-temperature data during the experiment.

Temperature and energy are in arbitrary units, but typically one would use ^oC and joules. Time is in units of seconds and is real time.
