What is the main cause of non -ideality in gases? Attractions between gas molecules. Gases are ideal. High temperatures that rip electrons from atoms. The individual volumes of each gas molecule.

## Step 1<br />The ideal gas law is a theoretical model that assumes gases behave perfectly. This model assumes that there are no intermolecular forces between the gas molecules and that the volume of the gas molecules is negligible compared to the total volume.<br /><br />## Step 2<br />However, in reality, gases do not behave perfectly according to the ideal gas law. This is because the assumptions of the ideal gas law are not entirely accurate.<br /><br />## Step 3<br />The main cause of non-ideality in gases is the attractions between gas molecules. This is because, in reality, gas molecules do interact with each other, which is not accounted for in the ideal gas law.<br /><br />## Step 4<br />The other options provided, such as gases being ideal, high temperatures that rip electrons from atoms, and the individual volumes of each gas molecule, do not directly contribute to the non-ideality of gases.
