1. When a substance has large or strongly attracted particles, they do not flow freely. For example, water flows very quickly compared to honey. Which property of liquids does this example illustrate?
A. Surface tension
B. Viscosity
C. Amorphousness
D. Crystallinity
2. Jamie notices that a glass of water can be filled slightly above the brown without spilling over the sides. This occurs because molecules below the surface of a liquid attract the ones above them, forming a skin on the surface. What is this affect called?
A. Surface tension
B. Viscosity
C. Reflectivity
D. Turbulence
3. Different types of solids behave differently due to their crystalline Structure. Which statement best describes plastic?
A. Plastic is an amorphous Liquid, because it does not melt at a specific temperature.
B. Plastic is a crystalline solid, because it melts at a distinct temperature.
C. Plastic is an amorphous solid, because it can be gradually heated and cooled to take on a specific shape.
D. Plastic is a crystalline liquid, because it does not melt at a distinct temperature.
