States of Matter: Basics



States of Matter: Basics is a free and portable gas simulation software for Windows. It basically lets you simulate and analyze characteristics of three forms of matter which are Solid, Liquid, and Gas. There are two tabs present on its main interface which let you perform solid, liquid, and gas simulation. Let’s see how.

States of Matter: Basics as Gas Simulator:

  • From the Solid, Liquid, Gas tab, choose Gas state. You can also select a particular atom or molecule to perform the gas simulation. The provided atoms and molecules are Argon, Neon, Oxygen, and Water. So basically, you can analyze the characteristics of these atoms and molecules in gas state.
  • Now, simply click the Play button to start the simulation. As we know, in the gas state, the atoms are way loosely held together. You can analyze this behavior and watch the gas particles freely moving in the vessel. It also provides a Step Play button to let you simulate gas state in one time step manner.
  • You can change the condition by applying Heat to the vessel or by Cooling it down. There is a slider provided to toggle between these two conditions.
  • A Temperature meter is provided on the main interface to let you have a watch over changing temperature according to the condition. You can switch between temperature units from Teacher menu (Kelvin or Celcius).

This is the basic gas simulation. To analyze temperature and pressure change graph with respect to changing behavior of gas particles, move to Phase Changes tab. Here, according to chosen atom or molecule, you can view a Temperature vs Pressure graph in a side panel. The graph represents states of matter and triple point and critical point. You can push the top of the given container to apply pressure on the particles present inside. Also, you can toggle between Hot and Cold conditions to visualize changes in different conditions. The change in temperature is also visible. When the pressure exceeds the critical limit, the container explodes and the gas particles move freely out of the container.

This gas simulator is a useful and interesting software for chemistry students. Not just gas, you can also analyze the behavior of other states of matter in different conditions.
