Liquids and solids are referred to as “condensed phases” because the attractive forces

A
cause molecules to become stationary.
B
leave little space between the molecules.
C
create large spaces between the molecules.
D
that hold the molecules together are negligible.
3

Which term best describes the substances that cause oil and water molecules in salad dressing to interact and mix?

A
surfactants
B
miscible liquids
C
immiscible liquids
D
compressed molecules
4

What happens as a result of the kinetic energy of the particles in a liquid being comparable with the intermolecular attractions between the particles?

A
The particles do not move enough to change positions, so the liquid is not compressible.
B
The particles move enough that they separate from one another and take the shape of their container.
C
The particles do not move enough, so they are fixed in place, and the liquid has a fixed volume.
D
The particles move enough that they are not fixed in place, and the liquid can flow.
5

What is produced on the top of a pool of water by the mutual attraction between water molecules?

A
surfactant
B
surface tension
C
a much smaller volume
D
a much higher density

Carla makes a small cardboard boat and floats it in a tub of water. When she adds a drop of dish soap behind the boat, the boat moves forward.Which statement best explains what happened?

A
The soap increased the viscosity of the water behind the boat, allowing the water in front of the boat to flow more easily.
B
The soap reduced the surface tension behind the boat, causing both water molecules and the boat to be pulled forward.
C
The soap increased the kinetic energy of the water molecules behind the boat, causing both the molecules and the boat to move forward.
D
The soap formed an immiscible layer on the water, causing the soap to spread out and push the boat forward.
7

Which process most likely takes place when the kinetic energy of molecules overcomes the intermolecular forces?

A
boiling
B
condensation
C
freezing
D
solidification
