3. How do liquid water, ice, and water vapor differ from each other?
a)
They are made of different kinds of atoms.
b)
They are are made of the same molecule moving in different ways.

4. Two beakers were prepared with 100 milliliters of water at two different temperatures, as shown above. Two drops of food coloring were then added carefully at the surface of each beaker of water. Which of the following best explains what would happen in this scenario and why?
a)
The food coloring would disperse the fastest in Beaker A because the molecules are widely spaced leaving space without matter for the dye to go.
b)
The food coloring would disperse the fastest in Beaker B because the dye acts like a catalyst, speeding up the movement of the water molecules.
c)
The food coloring would take the same amount of time to disperse in Beaker A and Beaker B because both contain water that behaves the same under the given conditions.
d)
The food coloring would disperse the fastest in Beaker B because the heat causes the water and dye molecules to move faster, increasing the number of molecular collisions that disperses the dye through the container.
13.
5. Approximately when does active boiling of the contents of the beaker occur?
a)
From the beginning of the process
b)
Between 2 and 6 minutes after the heating begins
c)
Between 6 and 16 minutes after the heating begins
d)
After approximately 16 minutes of heating
14.
2. Two white powders were mixed together. A chemical reaction occurred, and a yellow powder was formed. What is the relationship between the yellow powder and the white powders?
a)
The yellow powder is made up of the same kinds of atoms as the white powders, but the atoms are combined into different molecules.
b)
The yellow powder is made up of the same kinds of molecules as the white powders, but the molecules are a different color.
c)
The yellow powder was released from inside the atoms of the white powders.
