Chapter 10: Q31E (page 587)
Heat is added to ice at 0 °C. Explain why the temperature of the ice does not change. What does change?
First the phase changes from solid to liquid. With the remaining heat, the temperature of the water can rise.

Substance B is hard, does not conduct electricity, and melts at\({\rm{1200 ^\circ C}}\). Substance B is likely a(n): (a) ionic solid (b) metallic solid (c) molecular solid (d) covalent network solid
Pressure cookers allow food to cook faster because the higher pressure inside the pressure cooker increases the boiling temperature of water. A particular pressure cooker has a safety valve that is set to vent steam if the pressure exceeds \({\rm{3}}{\rm{.4 atm}}\). What is the approximate maximum temperature that can be reached inside this pressure cooker? Explain your reasoning.
On the basis of dipole moments and/or hydrogen bonding, explain in a qualitative way the differences in the boiling points of acetone \(\left( {{\bf{56}}.{\bf{2}}{\rm{ }}^\circ {\bf{C}}} \right)\)and \({\bf{1}}\)-propanol \(\left( {{\bf{97}}.{\bf{4}}{\rm{ }}^\circ {\bf{C}}} \right),\)which have similar molar masses.
Identify the following substances as ionic, metallic, covalent network, or molecular solids: Substance A is malleable, ductile, conducts electricity well, and has a melting point of\({\rm{1135 ^\circ C}}\). Substance B is brittle, does not conduct electricity as a solid but does when molten, and has a melting point of\({\rm{2072 ^\circ C}}\). Substance C is very hard, does not conduct electricity, and has a melting point of\({\rm{3440 ^\circ C}}\). Substance D is soft, does not conduct electricity, and has a melting point of\({\rm{185 ^\circ C}}\).
In terms of their bulk properties, how do liquids and solids differ? How are they similar?
