Solids, Liquids, Gases

Front

What is an amorphous solid?

Back

An amorphous solid is a solid that does not have a definite geometric shape or long-range order in its molecular structure. An example is glass.

Front

What defines the shape and volume of solids?

Back

The attraction between particles gives solids a definite shape and volume.

Front

What is sublimation?

Back

Sublimation is the process in which a solid changes directly into a gas without passing through the liquid state. An example is dry ice (frozen carbon dioxide).

Front

What is the melting point?

Back

The melting point is the temperature at which a solid begins to liquefy.

Front

What does the kinetic theory of matter state?

Back

The kinetic theory of matter states that all matter is composed of particles that are in constant motion.

Front

What is a crystalline solid?

Back

A crystalline solid is a solid material whose constituents are arranged in a highly ordered structure, forming a crystal lattice. Examples include salt and diamonds.

Front

What is the difference between a solid and a liquid?

Back

Solids have a definite shape and volume, while liquids have a definite volume but take the shape of their container.

Front

What is viscosity?

Back

Viscosity is a measure of a fluid's resistance to flow. Higher viscosity means a thicker fluid, like honey, while lower viscosity means a thinner fluid, like water.

Front

What is the boiling point?

Back

The boiling point is the temperature at which a liquid turns into vapor.

Front

What is a gas?

Back

A gas is a state of matter that has no definite shape or volume and expands to fill its container.
