  1. You can view and study changes in properties of the gas and Pressure, Volume, and Temperature parameters.
  2. It lets you analyze the change in speed of the gas particles as you change the temperature.
  3. As the pressure goes beyond a critical point, you will see the top door bursting out and gas particles moving freely out of the box.
  4. The gas particles will move freely when you add heat to the box and the particles will come together if the heat is removed. This way, you can analyze gas properties closely at different pressure and temperature.

Measurement Tools:

It provides various measurement tools to help you study and perform gas simulation more precisely.

  1. Layer Tool: Using this tool, you can view exact pressure at different heights of the box. And, you can also set averaging time.
  2. Ruler Tool: It can be used to measure or set the length of the box.

  4. Stopwatch: To see the exact time of gas simulation.
  5. Energy Histogram: This tool shows different graphical representation of various calculations including Kinetic Energy and Speed of heavy and light molecules. This is shown in real time as the simulation proceeds.
  6. Center of mass markers: As the name suggests, this tool marks the center of mass for heavy and light particles.

The good part of this gas simulator is that it comes in a portable package. Hence, you don’t need to go through an eventful installation process and can quickly launch and use it when required.

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.

Gas 2D Simulator

Gas 2D Simulator is another free gas simulation software for Windows. To start with, you can set up parameters including particles amount, width and height of container, radius of particles, mass of particles, and probability distribution. The units of different parameters are not clear in this software. After assigning aforementioned parameters, you can specify delay time for gas simulation.

From the Visualize tab, you can view the gas particles and their motion. Also, real-time statistics are visible on the interface itself. These statistics include calculations of events, crossings, collisions, average energy, and average speed.

In the Rayleigh tab, it shows the graphical representation of continuous probability distribution. You can change the scale parameter of the graph. The expected value and variance is calculated and shown in real time. There is a Velocity field tab which depicts the motion of gases. You can vary vector length as per your requirement.

Like other software, this is also a portable gas simulation software.

Ideal Gas with Maxwell's Demon

Ideal Gas with Maxwell’s Demon is another one of gas simulation software for Windows. What it does is basically simulating two-dimensional ideal gas monitored by Maxwell’s Demon. Maxwell’s Demon is a hypothetical character which lets particles which are faster than average move from right to left, while vice versa for slower than average particles. In this software, green particles are faster than average, while black ones are slower than average.

Its main interface contains a rectangular box which is divided into two parts. One part is colored with red, other with blue. The gas particles are spread throughout the box with random positions and velocities. On clicking a particle in the box, you can view its X and Y coordinates. It provides an N field to change number of particles in the box, which can be set up to 500. You can set the desired simulation speed in frame per second using the provided slider. You can turn on the Maxwell’s Demon by enabling the respective checkbox. Now, it lets you analyze the motion of green particles and black particles. If you want to perform gas simulation by one time step, use the step simulation button from the interface.

It provides a Temperature Plot option which plots the temperature for both the sides in the box in real time.

Ideal Gas with Maxwell’s Demon is a simple and basic gas simulator for Windows.

The Greenhouse Effect

The Greenhouse Effect is a different kind of gas simulator software for Windows. As the name of the software implies, this software is used to simulate greenhouse gases effects specifically. You can basically analyze the effect of greenhouse gases on the climate.

It shows sunlight photons and infrared photons in yellow and red, respectively. You can adjust greenhouse gas concentration by using the provided slider. Also, it lets you set atmosphere condition to today’s, 1750, or Ice Age. Based on chosen time period, the greenhouse gas composition is displayed which mainly include Water vapor (H2O), Carbon dioxide (CO2), Methane (CH4), and
Nitrous oxide (N2O). You can add a number of clouds too. Now, you can adjust the speed of greenhouse gas simulation and see the effect on the atmospheric temperature. You can then compare it to the effect of glass panes in Glass Layers tab. The temperature unit can be set to Celsius or Fahrenheit.

In the Photon Absorption tab, you can visualize how light interacts with molecules of Water vapor, Carbon dioxide, Methane, and Nitrogen. You can customize the number of molecules of these chemical compounds.
