(a)
Interpretation:
Identify the intermolecular forces that must be overcome to perform the following statement of melt ice.
Concept Introduction:
London dispersion force also called an induced dipole-induced dipole attraction is a temporary attractive force that results when the electrons in two adjacent atoms occupy positions that make the atoms form temporary dipoles.
Dipole-dipole interaction results when two dipolar molecules interact with each other through space, there occurs a partially negative charge of one of the polar molecules is attracted to the partially positive charge of the second polar molecule.
Ion-dipole interaction results of an electrostatic interaction between a charged ion and a molecule that has a dipole.
A hydrogen bonding is partially an electrostatic attraction between

Answer to Problem 1PS
In ice the water molecules are held together by hydrogen bonding network to from a three dimensional lattice.
Explanation of Solution
In water molecules the hydrogen bond in ice are linear and have strong directional property, this directionality indicate that hydrogen bonds in ice are as strong as a covalent bond. During melting few of these hydrogen bonds are melting to from water.
In water a

Answer to Problem 1PS
Iodine molecules are non-polar, only dispersion forces must be overcome.
Explanation of Solution
They sublime because though there are covalent bonds within molecule holding two iodine atoms together.
From this molecule Van der Waal’s forces are very weak interactions between molecules of a substance hence the iodine molecules easily escape from the solid structure easily.

Answer to Problem 1PS
Ammonia vaporization having hydrogen bonding was occurred.
Explanation of Solution
Ammonia is a polar molecule since the nitrogen atom is more electronegative than hydrogen, and the only intermolecular forces present are London dispersion force was occurred.
