Classifying Matter

100

What is anything that takes up space?

Matter

200

What are the three forms of matter

Solid, Liquid, and Gas 

300

What is a substance that consists of just one type of atom?

Element 

400

Explain the particles in a solid, liquid, and gas

Solid- Particles are packed tight together

Liquid- Particles are in between solid and gas

Gas- Particles are spread far apart 

500

What is the difference between heterogeneous mixture and homogeneous mixture?

Heterogeneous mixture is a type of mixture in which the individual substances are not evenly mixed

Homogeneous mixture is a type of mixture in which the individual substances are evenly mixed

Physical Properties

100

What is the amount of matter in an object?

Mass

200

What are the freezing points and boiling points of water?

Give both the Celsius and Fahrenheit measurements  

Freezing point: 32F 0C

Boiling Point: 212F 100C

300

Mass per unit volume of a substance 

Density 

400

What is solubility 

The ability of one substance to dissolve in water

500

If I have 50 grams of sugar and 150 grams of water when I dissolve the sugar in the water what will happen to the number of total grams? How many grams do we have total? 

You will 200 grams. The mass is neither gained or lost 

Physical Changes

100

Give three examples of physical changing

Crushing, tearing, ripping, smashing, freezing, and boiling are all examples of physical changes 

200

What is a change in size, shape, form, and state of matter in which a new substance is not created?

Physical Change

300

How do you speed up particles or slow particles down?

To speed particles up you add heat

To slow particles down you cool them 

400

A characteristic of matter that you can observe or measure without changing the the identity of the matter 

Physical property

500

Explain the shape and volume of a solid, liquid, and gas

Solid- Definite shape and definite volume 

Liquid- Definite volume and no definite shape

Gas- No definite shape and no definite volume

Chemical Changes

100

Give two examples of chemical changes

Burning, Rusting 

200

What is a change in matter in which the substances that make up the matter change into other substances with new physical and chemical changes?

Chemical change

300

What are three changes that occur in chemical changes? 

Bubbles, energy change, odor change, color change, heat is created

400

What is a characteristic of matter that can be observed as it changes to a different type of matter?

Chemical property 

500

The amount of substance in a certain volume 

Concentration
