SC 9 Chapter 1: Atomic theory explains the composition and

behaviour of matter.Name:_______________

1.2 Investigating Matter (Pages 16 – 27)Matter is anything that has ____________ and _______________.

______________ is the amount of matter in a substance or object - often measured in __________

______________ is the amount of space a substance or an object occupies- often measured in ____________

Chemical ChangeA chemical change is ________________________________________________

______________________________________________________________________________________________________________________

Changes of StateWhen _______________ changes occur, there may be a change in appearance but no new substances form. Changes of state are physical changes. The most common states of matter are:

_____________ is the state of matter that has a definite shape and volume _____________ is the state of matter that has definite volume, but its shape is

determined by its surroundings _____________ is the state of matter that has its shape and volume determined

by its surroundingsThe Particle Model of Matter____________________ includes facts and observations about matter, laws that summarize patterns of behaviour in matter, and theories that explain the patters of behaviour.

The Kinetic Molecular Theory_______________________________ is the energy of motion. The main points of the Kinetic Molecular Theory are:

1. _______________________________________________________________2. _______________________________________________________________3. Particles are constantly _______________. In ________________ and

________________ the particles are colliding with each other and the walls of the container.a) ____________________________________________________________

The Kinetic Molecular Theory and Changes of StateChanges of state occur when matter changes from a ______________, ______________ or ______________ to one of the other states of matter. The kinetic molecular theory helps explain changes of state, as well as the differences between solids, liquids and gases. The particles in cold objects have ____________________________________ and the particles simply vibrate __________________. The particles in warmer objects have more kinetic energy and move faster.Temperature and Changes of StateChanges of state depend on a number of factors, such as temperature. When ______________ particles gain kinetic energy and vibrate _____________. This causes them to move _______________ apart. If enough heat is added to a solid, it will _____________. Melting is the change of state from __________________________. The temperature at which an object melts is called the __________________________. Boiling is the change of state from ________________________. The temperature at which an object boils is called the ____________________._________________________ is the change of state from a gas to a liquid._________________ or ______________ is the change of state from a liquid to a solid.________________________ is changing from a solid to a gas_____________________ is changing from a gas to a solid

Describing Matter_________________________ are characteristics of matter that can be described but not measured.

Qualitative properties are _____________________________________________________________________________________________________

Quantitative properties ______________________________________________________________________________________________________

The usefulness of a substance depends on which properties it has, and sometimes which properties it does not have.

Pure SubstancesA pure substance is a substance that is made up of _____________________________. There are two kinds of pure substances: ________________ and _________________.

An __________________ is a pure substance that cannot be broken down or separated into simpler substances. Example:________________________

A ___________________ is a pure substance composed of at least two elements combined in a specific way. Example:___________________________
