Physical and Chemical Properties

What is a homogeneous mixture?

Back

A homogeneous mixture is a mixture in which the composition is uniform throughout, and individual components cannot be distinguished.

Front

What is a heterogeneous mixture?

Back

A heterogeneous mixture is a mixture in which the composition is not uniform, and individual components can be seen and separated.

Front

What is a suspension?

Back

A suspension is a type of heterogeneous mixture where solid particles are dispersed in a liquid but can settle over time.

Front

What is a colloid?

Back

A colloid is a mixture where very small particles of one substance are evenly distributed throughout another substance, and they do not settle out.

Front

What is a chemical property?

Back

A chemical property is a characteristic of a substance that can only be observed during a chemical reaction, such as reactivity or flammability.

Front

What is a physical property?

Back

A physical property is a characteristic of a substance that can be observed or measured without changing its chemical identity, such as color, boiling point, or density.

Front

What is boiling point?

Back

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

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 an example of a homogeneous mixture?

Back

An example of a homogeneous mixture is colored water, where the color is evenly distributed throughout the water.

Front

What is an example of a heterogeneous mixture?

Back

An example of a heterogeneous mixture is a salad, where the individual ingredients can be seen and separated.
