When dispersion forces is the only intermolecular force between a substance' molecules, this substance is usually a gas at room temperature, unless it is a big molecules
where it could be a liquid at room temperature. Why?
O dispersion forces are the moderate forces. However, when the molecules are big it becomes less effective
O dispersion forces are the weakest forces. However, when the molecules are big it becomes less effective
