Structure and Properties of Matter

What is matter?

• A single kind of matter that is pure and has a specific set of properties

• A characteristic of a substance that can be observed without changing it into another substance

• Anything that has mass and takes up space

• A neutral group of two or more atoms held together by covalent bonds

What defines a substance?

• A characteristic of a substance that describes its ability to change into different substances

• A single kind of matter that is pure and has a specific set of properties

• A measure of how much matter is in an object

• Two or more substances that are together in the same place but their atoms are not chemically bonded

What is a physical property?

• A characteristic of a pure substance that can be observed without changing it into another substance

• A measure of the force of gravity acting on an object

• The basic particle from which all elements are made

• A substance made of two or more elements chemically combined in a specific ratio or proportion

What is a chemical property?

• A characteristic of a substance that describes its ability to change into different substances

• The amount of space that matter occupies

• A neutral group of two or more atoms held together by covalent bonds

• A single kind of matter that is pure and has a specific set of properties

What is an atom?

• A pure substance that cannot be broken down into other substances by chemical or physical means

• The basic particle from which all elements are made; the smallest particle of an element that has the properties of that element

• A measurement of how much mass of a substance is contained in a given volume

• Two or more substances that are together in the same place but their atoms are not chemically bonded

• A pure substance that cannot be broken down into other substances by chemical or physical means

• A characteristic of a pure substance that can be observed without changing it into another substance

What is the difference between mass and weight?

• Mass is a measure of how much matter is in an object, while weight is the amount of space that matter occupies

• Mass is the amount of space that matter occupies, while weight is a measure of the force of gravity acting on an object

• Mass is a measure of how much matter is in an object, while weight is a measure of the force of gravity acting on an object

• Mass is a measure of the force of gravity acting on an object, while weight is the amount of space that matter occupies
