Genius Maker - School software - Chemistry software GAS LAWS

Features:

The Gas laws is a chemistry software, which facilitates to visualise and understand the universal gas laws namely, Boyles law, Charles law and Gay-lussac's law. In other words, this software helps students to understand the gas laws and the significance of the ideal gas law equation PV = nRT. The users can change the physical parameters as per their choice and see the effects with in an animated piston cylinder arrangement.

How to start with Gas Laws software ?

• Open Genius Maker software and click "Gas Laws" button. It opens the Gas Laws window.
• Boyles law is selected by default.
• You may see a Piston cylinder arrangement with gas particles inside.
• It is set for a default value of pressure and volume.
• Just click and drag the piston by using mouse to either side.
• You will see that the piston moves and hence the volume changes. You will also see that the pressure of the system changes in accordance with the Boyles law.
• The details of each section of Gas laws window are given below.
  • Select a law
    • This window is meant for selecting different laws are to play with various parameters to see their effect on real time mode.
  • Controls
    • This window hosts the control for parameters such as Pressure, Volume, Temperature and number of moles. The controls which are relevant to the selected law only will be displayed and the other parameters will be kept as constant by the software. (Please note that the users cannot change that constant values, because they are set to optimum values for easy understanding of the laws.)
  • Physical parameters
    • This window displays the current values of Pressure, Volume, Temperature and number of moles at any given point of time.
  • Definition window
    • The bottom right corner is the definition window, which displays the definition of the selected law.

BOYLES LAW

• Select Boyles law  from the "Select a law" window.

• NOTE: This process assumes that the temperature is kept at a constant value.

• Just click and drag the piston by using mouse to either side.

• You will see that the piston moves and hence the volume changes. You will also see that the pressure of the system changes in accordance with the Boyles law. Another way to change the volume is to move the volume slider from the controls window itself.

• Now you may try changing the pressure by using the pressure slider from the controls window. You will see that the volume of the system changes automatically in accordance with the Boyles law. 

CHARLES LAW

• Select Charles law  from the "Select a law" window.

• NOTE: This process assumes that the pressure is kept at a constant value.

• Just click and drag the piston by using mouse to either side.

• You will see that the piston moves and hence the volume changes. You will also see that the temperature of the system changes in accordance with the Charles law. Another way to change the volume is to move the volume slider from the controls window itself. You can see the change in velocity of the gas particles as temperature changes. 

• Now you may try changing the temperature by using the temperature slider from the controls window. You will see that the volume of the system changes automatically in accordance with the Charles law. 

GAY-LUSSAC'S LAW

• Select Gay-Lussac's law  from the "Select a law" window.

• NOTE: This process assumes that the volume is kept at a constant value.

• Since it is a constant volume process, the piston movement is arrested and hence you cannot click and drag the piston by using mouse.

• Change the pressure value by moving the pressure slider and you will notice that the temperature of the system also changes automatically in accordance with Gay-Lussac's law.

• Now you may try changing the temperature by using the temperature slider from the controls window. You will see that the pressure of the system changes automatically in accordance with Gay-Lussac's law. 

PLAY WITH PARAMETERS

• Select "Play with all parameters to see their effect"  from the "Select a law" window.

• IMPORTANT NOTE: This section is intended solely for students to understand the effect of any one parameter at a time. It does not reflect the behaviour of other parameters due to change in one parameter. Hence it is not a real life situation.

• You may move the pressure slider forward or backward to pressurise or depressurise.

• You may see what happens to the gas molecules.

• You may move the volume slider (or piston) forward or backward to increase or decrease volume.

• You may see what happens to the gas molecules.

• You may move the temperature slider forward or backward for cooling or for heating the gas.

• You may see what happens to the gas molecules.

• You may move the Number of mole slider forward or backward to increase or decrease the number of moles of gas particles present in the cylinder. 

• You may see what happens to the gas molecules.
