All matter can be classified as either an (one type of atom), a (two or more different types of atoms chemically bonded/combined) and (two or more different types of atoms that ARE NOT chemically bonded.)
Draw particle representations of each type of matter below.
Name of Type of Matter

Particle Representation

Which state of matter is being described for the next three questions:
This matter has a definite shape and a definite volume:
This matter has a definite volume and an indefinite shape:
This matter has an indefinite volume and an indefinite shape:
A super heated ionized gas is called a . This state of matter is found in the sun and other stars.
Describe the space between the particles and the motion of the particles for the next two questions:
Increasing the thermal energy in a substance causes the particles to:
Decreasing the thermal energy in a substance causes the particles to:
The average kinetic energy of a substance describes it’s .
The total or sum of kinetic energy of a substance describes it’s .
The transfer of thermal energy from one substance to another is called .
Thermal energy moves from substances to substances.
Matter is anything that has and .
True or false? The particles of solids vibrate in place.

Use the heating curve of water to complete the chart. (solid, liquid, gas, vaporizing, melting, freezing, condensing)

Matter can be described by its properties.
Properties that can be observed without trying to change the substance into a new substance are called .
Properties that can only be observed by trying to change or changing a substance into a new substance are called .
Identify the properties below as either chemical (C) or physical (P).
color

reactivity

texture

acidity

flammability

Length and volume

shape

State of matter

Matter can be changed both physically and chemically.
Changes that result in new substances with new properties are called .
Changes that do NOT result in new substances are called .
To KNOW: To know if a substance has undergone a chemical change you look for evidence. Evidence of chemical change includes:
Production of a gas (bubbling)
Color change (unexpected)
formation/production of a precipitate (formation of a solid)
change in odor
release or absorption of energy (light, sound or heat)

Identify the changes as either chemical (C) or physical (P). If chemical, what is the evidence?
Burning a piece of paper

Tearing a piece of paper

Digesting food

Heating a cup of water

Mixing baking soda and vinegar

Mixing calcium chloride and water

To KNOW: Chemical Changes are also called chemical reactions.
