Matter

Matter

1. Is anything that has mass and takes up space 2. All the "stuff" around you is matter, and you are matter too.

Physical Property

1. is a characteristic of a pure substance that can be observed without changing it into another substance. 2. Examples of physical properties of matter are freezing, melting, hardness, texture, color, and describing a substance as a solid, a liquid, or a gas. Also, whether or not a substance dissolves in water. 3.Physical properties can be used to classify matter.

Chemical Properties of Matter/Chemical Properties

1. is a characteristic of a pure substance that describes its ability to change into different substances 2. To observe the chemical properties of substance, you must try to change it to another substance. 3. Chemical Properties are burning and rusting.

Elements

1. is a pure substance that can not be broken down into any other substance by chemical or physical means. 2.Elements are the simplest substances. 3. Each element can be identified by its specific physical and chemical properties. 4. Elements are often represented by one- or two - letter symbols, such as C for carbon, O for oxygen, and H for hydrogen.

Properties of Matter/Chemistry

1. is the study of the properties of matter and how matter changes.

Examples (Physical Property)

:2 properties of metal are luster and the ability to conduct heat and electricity. Metals are also flexible and can be bent into shapes without breaking.

Elements/What Is an Element?

All matter is made up of elements.

Why is burning a Chemical Property?

Burning is a chemical property because when a substance burns, it combines with oxygen from the air to form mew substance.

How do Chemical Properties differ from Physical Properties?

Chemical Properties differ from physical properties because chemical properties can not be observed just by looking at a substance. The substance must combine with something else to form a new substance.

Substance

In chemistry, a substance is a single kind of matter that is pure (meaning it always has a specific makeup, or composition, and a specific set of properties). *Every form of matter has two kinds of properties: 1. Physical Properties 2. Chemical Properties

How do you observe a chemical property?

In order to observe a chemical property of a substance you must try to change the substance to another substance.

How do you know that water is a pure substance?

It is a single kind of matter with its own makeup and properties.

Why are melting or freezing a Physical Property?

Melting or freezing is a physical property because it only changes the form of the substance and not the substance.

Why are melting and freezing physical properties?

Water has not changed into a different substance it has only changed forms.

Example of Physical Property (Iron Rust)

When iron rusts, it combines with the oxygen in the air. The new substance that is produced is rust or iron oxide (FE203).

Example of Physical Property (Wood Burning)

When wood burns, it combines with oxygen (O2) in the air. The new substance that are produced in burning are carbon dioxide (CO2), ash, and water (H2O).
