5th Grade Matter Flashcard

Front

What is a homogeneous mixture?

Back

A homogeneous mixture is a mixture that has a uniform composition throughout, meaning that the different components are not distinguishable. An example is a solution, like saltwater.

Front

What are physical properties of matter?

Back

Physical properties of matter are characteristics that can be observed or measured without changing the substance's chemical identity. Examples include color, mass, volume, and density.

Front

Which of the following is NOT a physical property of matter: Magnetism, Mass, Density, or Flammability?

Back

Flammability is NOT a physical property; it is a chemical property that describes how a substance reacts with fire.

Front

What is one sign of a chemical change?

Back

One sign of a chemical change is an unusual change in color, temperature, or odor.

Front

What happens when a gas changes into a solid?

Back

The process is called deposition.

Front

What is a solution?

Back

A solution is a homogeneous mixture where one substance (the solute) is dissolved in another (the solvent), such as sugar in water.

Front

What is the difference between a physical change and a chemical change?

Back

A physical change alters the form or appearance of a substance without changing its chemical composition, while a chemical change results in the formation of new substances.

Front

What is density?

Back

Density is the mass of a substance divided by its volume, often expressed in grams per cubic centimeter (g/cm³). It helps determine whether an object will float or sink in a fluid.

Front

What is an example of a physical change?

Back

An example of a physical change is ice melting into water.

Front

What is a colloid?

Back

A colloid is a mixture where tiny particles of one substance are evenly distributed throughout another substance, such as milk.
