• The boiling points of compoundscontaining elements in the same periodicgroup is inversely proportional to theelement's molar mass.• When adhesion is greater than cohesion,a convex appearance of the liquid in atube is evident.• When cohesion is greater than adhesion,a concave appearance of the liquid in atube is evident.• if water has no ability to form hydrogenbonds, it would be gas at roomtemperature.• The attractive interaction between an ionand the induced dipole is called ion-induced dipole force.• A polar molecule placed near an atomcauses distortion of the electron cloud ofthe atom resulting to a dipole.• Polarizability prevents gases containingnon polar molecules to condense.• Hydrogen bond is stronger than covalentbond. Assess the correctness of each of thestatements.TRUE OR FALSEThe three states of matter can beinterconverted without changing thesubstance's composition.• A substance is a matter that has indefinitecomposition but with distinct properties.• Color, melting point, density and boilingpoint are physical properties of matter• We cannot recover hydrogen and oxygenfrom water by a physical change likeboiling or freezing.• Intramolecular forces hold atoms togetherin a molecule.• In order to evaporate a liquid, much lessenergy is needed than to to break thebonds in the liquid's molecules.• Molecules with temporary dipole momenttend to align with opposite polarities in thesolid phase for maximum attractiveinteraction.
