Illustration Procedure/Observation/Discussion Procedure: Simply blow up two balloons to equal size, place one on ice and one in just boiled water. What happened to the volume of the balloons? Observation: (1)_ Discussion: The increase in temperature will force the air to increase its (2). thus expanding the balloon. It will look like the balloon is growing or inflating inside the container with hot water Figure 2 Balloons in hot and cold water

A solution is made by adding 50.0 mL of ethanol (C2H5OH, d = 0.789 g/mL) to 50.0 mL of water (d = 0.998 g/mL). What is the total vapor pressure over the solution at 20 C? (See Study Question 75.) The vapor pressure of ethanol at 20 C is 43.6 mm Hg.
Why do liquids have a vapor pressure? Do all liquids have vapor pressures? Explain. Do solids exhibit vapor pressure? Explain. How does vapor pressure change with changing temperature? Explain.
If a piece of filter paper (an absorbent paper used in laboratories) is suspended above a beaker of water and just touching the surface, water will slowly move up the paper. What is the name given to this phenomenon, and how is this behavior explained?
When water is placed in a buret it forms a concave meniscus at the surface. In contrast, mercury (in a manometer for example) forms a convex meniscus (Figure 11.17). Explain why this phenomenon occurs, and why the two liquids give different results. Predict the meniscus shape if the buret is filled with ethylene glycol (HOCH2CH2OH). Meniscus Water in glass tubes (right) is attracted to the polar OH groups on the surface of glass and so water forms a downward facing or concave meniscus. Mercury, however, is not attracted to the glass surface, and so forms a convex meniscus (left).

Cooking oil floats on top of water. From this observation, what conclusions can you draw regarding the polarity or hydrogen-bonding ability of molecules found in cooking oil?
