Van der Waals equation Calculator

The Van der Waals equation is a modification of the ideal gas law to account for the volume occupied by gas molecules and the attractive forces between them. It is expressed as:

Where:

• $P$ is the pressure of the gas.
• $V$ is the volume of the gas.
• $T$ is the temperature of the gas.
• $R$ is the ideal gas constant.
• $a$ and $b$ are Van der Waals constants specific to the gas.
