Van der Waals equation
The Van der Waals equation is a mathematical formula that describes how real gases behave, taking into account interactions between gas molecules and the volume they occupy. Unlike the ideal gas law, which assumes gas particles have no size and do not attract one another, the Van der Waals equation adjusts for these factors. It helps predict the pressure, volume, and temperature of gases more accurately, especially under high pressure or low temperature, where deviations from ideal behavior are significant. Essentially, it provides a better understanding of gas behavior in real-world conditions.

The Van der Waals equation is an adjustment of the ideal gas law, used to describe how real gases behave under various conditions. It accounts for two main factors: the volume of gas particles themselves and the attractive forces between them. In simpler terms, while the ideal gas law assumes gases have no size and do not interact, the Van der Waals equation provides a more accurate representation by recognizing that gas particles occupy space and can influence each other. This makes it useful for understanding gases in scenarios where pressure and temperature are extreme.
