Question
Chapter 11, Problem 36AC
To determine
From the following options, salt solutions freeze at a lower temperature than pure because:
(a) more ionic bonds are present.
(b) salt solutions have a higher vapor pressure.
(c) ions get in the way of water molecules trying to form ice.
(d) salt naturally has a lower freezing point than water.

Explain the differences in boiling point in terms of intermolecular forces
(IMF).
a. HF (20° C) and HCl (-85° C)
b. CHCl3 (61° C) and CHBr3 (150° C)
c. Br2 (59° C) and ICl (97° C)
2. Which statement best describe gases?
a. Gases consist of molecules that have enough spatial separation that the intermolecular
bonding characteristics of liquids and solid is absent.
b. Gases are almost incompressible. In liquids molecules are close to each other.
c. Gases are characterized by structural rigidity and resistance to a force applied to the
surface.
d. Gases are in the state in which matter adapts to the shape of its container but varies only
slightly in volume
5. The number of substitutional atoms or ions in the structure remains
nearly constant, even when the temperature is changed.
6. Failure occurs in brittle materials as a result of the formation of
internal cracks that cannot be seen from the outside.
True or false
7. In Interstitial mechanism, the atoms exchange places through
rotation about a mid-point. The activation energy for the process is
very high.
8. A higher yield point reveals greater hardness of the metal. A higher
value of the maximum stress point shows that the metal is a
stronger one.
