Notes ? Matter Describing Matter Definition - Anything that has mass and takes up space. Matter can be in three states (plasma is another state but exists at high energy that we will not deal with) Solid ? definite shape, definite volume, particles packed closely together Liquid ? indefinite shape, definite volume, particles can flow easily Gas/Vapor ? indefinite shape, indefinite volume, particles are spaced far apart Similar terms but not interchangeable Gases exist as gases at room temperature Vapors are in a gaseous state but generally exist as solids or liquids Characteristic/Physical Properties Physical Properties ? characteristics that are observed but never change for a substance Boiling point (condensation) - temperature at which a liquid turns to a vapor

AP Biology Summer Assignment Unit 2: The Chemistry of Life Ch. 2- Write the key concepts from chapter 2 (include concept number also). These are listed for you in the front of each chapter. The key concepts from chapter 2 are concept 2.1 which states, ?Matter consists of chemical elements in pure form and in combinations called compounds.? Concept 2.2 which states, ?An element?s properties depend on the structure of its atom.? Concept 2.3 which states, ?The formation and function of molecules depend on chemical bonding between atoms.? And lastly concept 2.4 which states, ?Chemical reactions make and break chemical bonds. Ch. 3- Use illustrations to describe how the structure of a water molecule allows it to form hydrogen bonds with other water molecules.

Determined by: Physical properties Chemical properties Physical Properties Physical properties can be measured without changing the material into another substance. They describe how a substance is by itself. The following terms are examples of physical properties: density density describes how the particles are packed into a material malleability malleability

Warm-Up Your car's gas tank holds 18.6 gallons and is one quarter full. Your car gets 16 miles/gal. You see a sign saying, "Next gas 73 miles." Your often-wrong brother, who is driving, is sure you'll make it without running out of gas. You're not so sure and do some quick figuring: Matter and Change Matter: Anything that has mass and takes up space. Mass: measure of the amount of matter. Matter and Change Atoms: Smallest unit of an element that maintains the properties of that element Elements: pure substance made of one atom. Compounds: made of atoms of two or more elements that are chemically bonded Physical properties and changes Physical properties: quality or condition of a substance that can be observed or measured without changing the substance

Pre-AP Chemistry Modern Chemistry (2006) Chapter 1 Notes ? Matter and Change 1.1 Chemistry is a Physical Science 1. The natural sciences were once divided into two categories: biological and physical sciences. 2. The biological sciences focus on living things and their interaction with the environment. 3. The physical sciences focus is mainly on non-living things. 4. However, chemistry is central to all living and non-living things because they consist of chemical structures. 5. Chemistry is the study of the composition, structure, and properties of matter, the processes that matter undergoes, and the energy changes that accompany these processes. Branches of Chemistry 1. Chemistry includes six branches of study ? although these branches often overlap.
