(a)
Interpretation:
The effect of increased strength of intermolecular forces on boiling point of liquids has to be determined.
Concept Introduction:
Dipole-dipole interactions come into play when partial charges of different dipoles interact with each other. Higher polarity between molecules more will be dipole-dipole interactions between them and vice-versa. Boiling point is governed by strength of dipole-dipole interactions that is measured in terms of dipole moments. Boiling point is directly related to dipole moment of molecules. More dipole moment of molecules, higher will be boiling point and vice-versa.
(b)
Interpretation:
The effect of increased temperature on viscosity of liquids has to be determined.
Concept Introduction:
Viscosity is characteristic property of liquid particles that allows resistance to their flow. In other words, it represents opposition to flow of liquids.
(c)
Interpretation:
The effect of increased temperature on surface tension of liquids has to be determined.
Concept Introduction:
Refer to part (a).
