States of Matter

What is the process called when a substance changes from a solid to a liquid?

• Freezing

• Condensation

• Sublimation

• Melting

What is the crystal structure of a solid?

• The crystal structure of a solid is only determined by its color

• The crystal structure of a solid can be classified into several types, including cubic, hexagonal, tetragonal, orthorhombic, monoclinic, and triclinic structures.

• The crystal structure of a solid is irrelevant to its physical properties

• The crystal structure of a solid is always amorphous

What are the properties of gases?

• Gases do not expand to fill their container

• Gases have no definite shape or volume, expand to fill their container, are compressible, and have low density.

• Gases are not compressible and have high density

• Gases have a definite shape and volume

What are the properties of liquids?

• Liquids do not take the shape of their container

• Liquids cannot flow and remain in the same shape

• Liquids have a definite shape and volume

• Liquids have the ability to flow and take the shape of their container. They also have a definite volume but no definite shape.

What are the properties of solids?

• Definite shape and volume, strong intermolecular forces, closely packed particles

• Definite shape and volume, weak intermolecular forces, closely packed particles

• Definite shape but no volume, weak intermolecular forces, closely packed particles

• No shape or volume, weak intermolecular forces, loosely packed particles

What type of structure do giant molecular structures have?

• Hydrogen network structure

• Metallic network structure

• Covalent network structure

• Ionic network structure

What type of structure do metallic lattices have?

• Loosely packed structure with localized electrons

• Randomly arranged structure with delocalized electrons

• Regularly spaced structure with localized electrons

• Closely packed structure with delocalized electrons

What type of structure do simple molecular structures have?

• Covalent bonds

• Hydrogen bonds

• Ionic bonds

• Metallic bonds

What are fullerences?

• Molecules composed entirely of carbon

• Molecules composed entirely of oxygen

• Molecules composed entirely of nitrogen

• Molecules composed entirely of hydrogen

What type of structure do ionic lattices have?

• Random arrangement of positive and negative ions

• Single-dimensional repeating pattern of positive and negative ions

• Three-dimensional repeating pattern of positive and negative ions

• Two-dimensional repeating pattern of positive and negative ions
