Matter

100

This exists as mixtures, solutions, elements, or compounds.

Matter

200

Matter exists in this many phases

Four; solid, liquid, gas, & plasma

300

Gas, liquid, solid, and this are phases of matter

Plasma

400

Based on the amount of stress applied on an object, can it act as both a liquid and solid?

Yes, an example being oobleck, when applied with little pressure, it is a liquid, when applied with heavy pressure, it is a solid.

500

These are the four classes of matter

Mixtures, solutions, elements, or compounds

Mixtures

100

This is matter that consists of two or more substances blended together but not chemically combined.

Mixture

200

The substances in mixtures are not this type of combination

Chemical

300

Chemical composition stays the same, but this type of composition changes, examples being the boiling point or melting point

Physical composition

400

In this type of mixture, the particles in the mixture are not very recognizable.

Homogeneous mixture

500

What type of mixture is this

Heterogeneous mixture

Solutions

100

This is a type of homogeneous mixture formed when one substance dissolves in another

Solution

200

This is a solution of oxygen and other gases dissolved in nitrogen. (Hint: It helps keeps you alive)

Air

300

This is the substance that dissolves

Solute

400

This is the substance that does the dissolving

Solvent

500

In lemonade with juice, water, and sugar, the solvent is this one

Water

Elements

100

This is the simplest pure substance and cannot be changed into a simpler substance by heating or by any chemical process.

Element

200

This is made up of only one kind of element and has definite properties.

Pure substance

300

Iron is made up of one material, so if you melt the iron by applying heat, it will make it a simpler substance.

False, it's already a simple substance

400

The smallest part of an element is this, which has the properties of that element.

Atom

500

The smaller particles in atoms share the same properties of the element they make up.

False, they don't share the same properties of the element they make up.

Compounds

100

Pure substances that are made up of more than one element are called this.

Compounds.

200

This is the chemical formula of water.

H₂O

300

Instead of writing the chemical's full name, you can write this, an abbreviation of the chemical.

Chemical Symbol

400

Most compounds are made up of this, which is two or more atoms chemically bonded together.

Molecules

500

_H₂ +_O₁=_HO
