VanCleave  Try New Approaches  Does temperature affect the
diffusion of the amine vapor? Repeat the experiment two times,
first setting the cups in bowls of ice water, and then placing
them in bowls of hot water.  Design Your Own Experiment      1.
Demonstrate the fact that water molecules are in constant
motion. Mix together in a 1-quart (1-liter) jar, 1 teaspoon (5
ml) of sodium chloride (table salt), five drops of green food
coloring, and 1 cup (250 ml) of water. Tilt the jar and slowly
pour a second cup (250 ml) of water down the inside of the jar.
The result is a layer of green water covered by a layer of clear
water (see Figure 22.2). Place the jar where it can remain
undisturbed for three days. Observe the contents of the jar as
often as possible. The motion of the water molecules is evident
as the two layers start to mix. The end result is a uniformly
green-colored liquid.
