(a)
Interpretation:
The symbol ΔvapH needs to be described.
Concept introduction:
Enthalpy of vaporization, ΔvapH is the amount of energy required to convert certain quantity of liquid into gas.
(b)
Interpretation:
The symbol Tc needs to be described.
Concept introduction:
Critical temperature is temperature at which the liquid and vapor interface become indistinguishable.
(c)
Interpretation:
The term instantaneous dipole needs to be defined.
Concept introduction:
Instantaneous dipoles are responsible for the forces known as dispersion forces/London force. This is the weakest intermolecular force among the other forces.
(d)
Interpretation:
The term coordination number needs to be defined.
Concept introduction:
Each atom inthe crystal is in contact with several other atoms in their structural units.
(e)
Interpretation:
The term unit cell needs to be defined.
Concept introduction:
Crystal structures are described according to the arrangements of particles in the unit cell.
