Crystalline and Amorphous Solids

What is the basic repeating unit of a crystal lattice structure called?

• unit cell

• atom

• crystal

• molecule

How are the particles arranged in an amorphous solid?

• Loosely packed and unordered

• Random or disordered

• Arranged in a perfect crystal lattice

• Aligned in a specific pattern

What is the main difference between crystalline and amorphous solids in terms of their atomic arrangement?

• Crystalline solids have a disordered and random atomic arrangement, while amorphous solids have a highly ordered and repeating atomic arrangement.

• Crystalline solids and amorphous solids have the same atomic arrangement.

• Crystalline solids have a liquid-like atomic arrangement, while amorphous solids have a solid-like atomic arrangement.

• Crystalline solids have a highly ordered and repeating atomic arrangement, while amorphous solids have a disordered and random atomic arrangement.

Give an example of a crystalline solid and an amorphous solid.

• Example of a crystalline solid: Wood

• Example of a crystalline solid: Diamond, Example of an amorphous solid: Glass

• Example of a crystalline solid: Plastic

• Example of an amorphous solid: Ice

What are some common applications of crystalline solids?

• Liquid state

• Gas state

• Plasma state

• Semiconductors, jewelry, electronic devices, and structural materials

What are some common applications of amorphous solids?

• Glass, plastics, and ceramics

• Concrete, rubber, and fabric

• Diamond, graphite, and steel

How does the melting point of crystalline solids compare to that of amorphous solids?

• The melting point of crystalline solids is higher

• The melting point of crystalline solids is lower

• The melting point of amorphous solids is higher

• The melting point of both types of solids is the same

What is the term used to describe the ability of crystalline solids to break along specific planes?

• cleavage

• solidification

• fusion

• fracture

What is the term used to describe the ability of amorphous solids to flow over time?

• viscosity

• density

• transparency

• elasticity

How do the physical properties of crystalline and amorphous solids differ?

• Crystalline solids have a disordered atomic arrangement, no distinct melting points, and no cleavage planes, while amorphous solids have a regular and repeating atomic arrangement, distinct melting points, and cleavage planes.

• Crystalline solids have a disordered atomic arrangement and no distinct melting points, while amorphous solids have a regular and repeating atomic arrangement, distinct melting points, and cleavage planes.
