Unit 1 - Matter

What is a colloid?

Back

A colloid is a mixture where tiny particles of one substance are evenly distributed throughout another substance, but they do not settle out. Examples include milk and fog.

Front

What is a solution?

Back

A solution is a homogeneous mixture where one substance (the solute) is completely dissolved in another substance (the solvent). An example is sugar water.

Front

What describes the particles in a solid?

Back

In a solid, particles are closely packed together and can only vibrate in place, which gives solids a definite shape and volume.

Front

What is a heterogeneous mixture?

Back

A heterogeneous mixture is a mixture where the components can be seen and are not uniformly distributed. An example is chunky spaghetti sauce.

Front

What is deposition in terms of matter?

Back

Deposition is the process where gas transforms directly into a solid without becoming a liquid first. An example is frost forming on a cold surface.

Front

What is a suspension?

Back

A suspension is a heterogeneous mixture where solid particles are dispersed in a liquid but can settle out over time. An example is muddy water.

Front

What is the difference between a homogeneous and heterogeneous mixture?

Back

A homogeneous mixture has a uniform composition throughout (like saltwater), while a heterogeneous mixture has distinct, separate components (like salad).

Front

What happens to particles in a liquid?

Back

In a liquid, particles are close together but can move past one another, allowing liquids to flow and take the shape of their container.

Front

What is vaporization?

Back

Vaporization is the process of turning from a liquid into a gas, which can occur through boiling or evaporation.

Front

What is sublimation?

Back

Sublimation is the process where a solid changes directly into a gas without passing through the liquid state. An example is dry ice turning into carbon dioxide gas.
