Matter and its Interaction

Matter that has uniform characteristics throughout is called ______.

• homogeneous matter

• heterogeneous matter

• compound

• mixture

Answer explanation

Matter that has uniform characteristics throughout is called homogeneous matter. This means its composition is consistent, unlike heterogeneous matter, which has distinct, separate components.

Matter that has parts with different characteristics is called ______.

• heterogeneous matter

• homogeneous matter

• pure substance

• element

Answer explanation

Matter with parts that have different characteristics is known as heterogeneous matter. This contrasts with homogeneous matter, which has a uniform composition throughout.

A characteristic by which a variety of matter is recognized is called a(n) ______.

• property

• element

• compound

• mixture

Answer explanation

A characteristic by which a variety of matter is recognized is called a property. Properties can include color, density, and boiling point, which help identify and differentiate substances.

A characteristic that depends upon the amount of matter in the sample is called a(n) ______.

• extensive property

• intensive property

• chemical property

• physical property

Answer explanation

An extensive property is one that changes with the amount of matter in a sample, such as mass or volume. In contrast, intensive properties, like density, do not depend on the amount of substance. Thus, the correct answer is extensive property.

A characteristic that does not depend upon the amount of matter is called a(n) ______.

• intensive property

• extensive property

• chemical property

• physical property

Answer explanation

An intensive property is a characteristic that does not change with the amount of matter present, such as density or boiling point. In contrast, extensive properties depend on the quantity of matter, making 'intensive property' the correct choice.

A characteristic that can be observed without producing new kinds of matter is called a(n) ______.

• physical property

• chemical property

• reactive property

• biological property

Answer explanation

A physical property can be observed without changing the substance's chemical structure, unlike a chemical property, which involves reactions that produce new matter. Therefore, the correct answer is 'physical property'.

Liam is conducting an experiment to observe how a substance reacts when mixed with another. The characteristic that depends on how this kind of matter changes during interactions with other kinds of matter is called ______.

• chemical property

• physical property

• thermal property

• electrical property

Answer explanation

A chemical property describes how a substance interacts with other substances, leading to changes in its chemical structure. This distinguishes it from physical properties, which do not involve such changes.

A simple substance that cannot be broken down into other substances by chemical means is called ______.

• element

• compound

• mixture

• solution

Answer explanation

An element is a pure substance that cannot be broken down into simpler substances by chemical means. In contrast, compounds are made of two or more elements, mixtures consist of multiple substances, and solutions are homogeneous mixtures.

A chemical combination of simple substances is called ______.

• compound

• mixture

• element

• solution

Answer explanation

A chemical combination of simple substances forms a compound, which has distinct properties different from the individual elements. In contrast, mixtures and solutions involve combinations without chemical bonding.

A physical combination of different substances that retain their individual properties is called a(n) ______.

• mixture

• compound

• element

• solution

Answer explanation

A mixture is a physical combination of substances that retain their individual properties, unlike a compound where substances chemically combine. Therefore, the correct answer is 'mixture'.
