States of Matter is a Java based simulation application designed to enable you to watch different types of molecules form a solid, liquid, or gas. Add or remove heat and watch the phase change.
Change the temperature or volume of a container and see a pressure-temperature diagram respond in real time. Relate the interaction potential to the forces between molecules.
Here are some key features of "States of Matter":
· Describe a molecular model for solids, liquids, and gases.
· Extend this model to phase changes.
· Describe how heating or cooling changes the behavior of the molecules.
· Describe how changing the volume can affect temperature, pressure, and state.
· Relate a pressure-temperature diagram to the behavior of molecules.
· Interpret graphs of interatomic potential.
· Describe how forces on atoms relate to the interaction potential.
· Describe the physical meaning of the parameters in the Lennard-Jones potential, and how this relates to the molecule behavior.
Requirements:
· Java
What's New in This Release: [ read full changelog ]
· Publication of the States of Matter Basics version to the production web site.
· Changed the "0" label on the middle of the stove to be just a tick mark.
· Changed labels on stove to say "Heat" and "Cool" and internationalized these labels.
· Modified the stove to be one large unit with a vertical slider on the front.
· Added a key handler that allows the user to make use of the arrow keys to control the amount of heating or cooling.
· Changed repulsive force arrow on the Atomic Interactions tab to be magenta to make it more distinct from the attractive force arrow.
· Moved "Kelvin/Celsius" option from "Options" menu into "Teacher" menu
· Made it so the selected atom/molecule changes when clicking on the image next to the radio button in the control panel
· Changed Argon color from blue-green to pink
· Fixed an issue where the clock would remain paused after the reset button was pressed. This was true on all tabs.
· Added a "Teacher" menu and added an option for setting the background to be white on all...
