1. 1. A glass flask filled with paraffin is placed in a hot water bath. The liquid level in the capillary tube first drops slightly before it rises. What is the reason for this initial dip?

   • A. The paraffin contracts when it first meets the hot water
   • B. The glass flask heats and expands first, increasing its capacity before the liquid warms
   • C. The capillary tube becomes narrower when heated
   • D. The rubber stopper absorbs some of the liquid

2. 2. A glass flask is filled with paraffin and heated. The apparent volume increase of the paraffin is 3.60 cm^3 and the glass flask expands by 0.12 cm^3. Calculate the real volume expansion of the paraffin.

   Type your answer (in cm^3) in the lesson.

3. 3. A flask of water is heated. The real volume increase of the water is 0.92 cm^3 and the flask itself expands by 0.08 cm^3. What is the apparent volume increase seen in the tube?

   Type your answer (in cm^3) in the lesson.

4. 4. Which list shows the substances in order from the lowest to the highest volume expansivity?

   • A. Mercury, Pyrex glass, Paraffin, Ethanol
   • B. Pyrex glass, Mercury, Paraffin, Ethanol
   • C. Pyrex glass, Paraffin, Mercury, Ethanol
   • D. Ethanol, Paraffin, Mercury, Pyrex glass

5. 5. Liquids expand more than solids for the same temperature rise because the forces between their particles are weaker. What type of forces are these?

   Type your answer in the lesson.
