10) When a substance goes from its solid phase into its liquid phase, the strength of its IMF changes. Yes or No. If it is No, then what is different?
11) List the species/particles (e.g. ionic compound, non-polar molecules, polar molecule, metals) from highest IMF to lowest IMF. Note: Some species may be equal to each other so put them together in your list.
