Question 1: A student put a bottle of water and a can of sugared soda in the freezer to chill them quickly. When she took them out, the bottle of water was frozen but the can of soda was not. Explain why this happened.

Question 2: Table sugar (C12H22O11) and table salt (NaCl) look very similar but have very different properties. Compare the properties of the two solids in the following areas.

  • Electrical conductivity of solid versus melted states
  • Attractive forces holding the solid together

Question 3: A passenger on an airplane finished a 0.5 L bottle of water during the flight and replaced the lid. The cabin pressure and temperature were maintained at 0.75 atm and 22°C during the flight. After landing, he noticed his empty water bottle had collapsed. (8 points)

  • How many moles of gas were in the water bottle?
  • If the pressure after landing was 1.0 atm, what was the volume of the passenger's collapsed water bottle? (Assume the bottle collapsed easily and temperature didn't change.)
