Matter, Properties, Changes Unit 2 Chem

What is an Alloy?

• A homogeneous mixture of metals
• Element number 37
• a homogeneous mixture of liquids
• a solid piece of copper

Chemical property

• the study of matter and the changes it under goes
• anything that has mass and takes up space
• the ability or inability of a substance to combine with or change into one or more new substances

Chemical change

• When an ice cube melts and turns into liquid water
• A process where one or more substances change to a new substance

The study of matter and the changes it under goes

• Physical Property

• Alloy
• Element

Extensive Property

• Anything that has mass and takes up space
• A homogeneous mixture
• A physical property that is dependent on the amount of substance present

Heterogeneous mixture

• Matter that does not have a uniform composition; can be separated by physical means
• Matter that has a uniform composition throughout; can be separated by physical means
• Matter that has a uniform and unchanging composition. Includes elements and compounds

Homogeneous mixture

• Matter that does not have a uniform composition; can be separated by physical means
• Matter that has a uniform composition throughout; can be separated by physical means
• A substance that does the disolving in a solution

Intensive property

• Matter that does not have a uniform composition; can be separated by physical means
• a physical property that remains the same no matter how much substance is present
• A physical property that is dependent on the amount of substance present
