Question

Which description best fits a gas? definite shape and volume; strong intermolecular attractions definite volume; shape of container; moderate intermolecular attractions definite volume; shape of container; weak intermolecular attractions volume and shape of container; no intermolecular attractions volume and shape of container; strong intermolecular attractions?

Answer 1

The answer is weak intermolecular attractions volume and shape of container. The molecules of gases have high kinetic energy compared to those of liquids and solids hence they are farther apart from one another. This results to weak intermolecular forces. Gases also expand to fit the container hence have no definite shape or volume.
