Question
• The boiling points of compounds containing elements in the same periodic group is inversely proportional to the element's molar mass. • When adhesion is greater than cohesion, a convex appearance of the liquid in a tube is evident. • When cohesion is greater than adhesion, a concave appearance of the liquid in a tube is evident. • if water has no ability to form hydrogen bonds, it would be gas at room temperature. • The attractive interaction between an ion and the induced dipole is called ion- induced dipole force. • A polar molecule placed near an atom causes distortion of the electron cloud of the atom resulting to a dipole. • Polarizability prevents gases containing non polar molecules to condense. • Hydrogen bond is stronger than covalent bond.

Assess the correctness of each of the statements. TRUE OR FALSE The three states of matter can be interconverted without changing the substance's composition. • A substance is a matter that has indefinite composition but with distinct properties. • Color, melting point, density and boiling point are physical properties of matter • We cannot recover hydrogen and oxygen from water by a physical change like boiling or freezing. • Intramolecular forces hold atoms together in a molecule. • In order to evaporate a liquid, much less energy is needed than to to break the bonds in the liquid's molecules. • Molecules with temporary dipole moment tend to align with opposite polarities in the solid phase for maximum attractive interaction.
