18
Q

Matter

A

Something that has mass and takes up space.

19
Q

States of Matter

A

A physical form of matter, which includes solid, liquid, and gas.

20
Q

Change of State

A

Change of substance from one physical state to another.

21
Q

Solid

A

Solid is a state of matter that has its own fixed shape, and its particles vibrate in its place and has a fixed shape.

22
Q

Liquid

A

Liquid is a state of matter that doesn’t have its own shape, and its particles are irregular and can slide past each other.

23
Q

Gas

A

Gas is a state of matter that doesn’t have its own shape, and its particles are irregular and move freely in all directions.

24
Q

Particle Theory of Matter

A
  1. All matter is made up of tiny particles.
  2. The particles have spaces between them
  3. The particles of matter are always moving
    (attracted each other).
  4. Adding heat to matter makes the particles move faster.
25
Q

Materials

A

Materials are the different types of matter things are made of, like wood, plastic, cotton, glass, rubber, and metal.

26
Q

Element

A

An element is a substance that cannot be split into anything simpler. There are 92 types of elements found naturally on Earth.

27
Q

Location of Elements in the Periodic Table

A

In the Periodic Table, metals are on the left and non-metals are on the right.

28
Q

Physical Properties of Metal

A

State and appearance, sonority, conduction of heat and electricity, strength, hardness, high density, flexibility, malleability, and ductility.

29
Q

Gold

A

Gold is a shiny, yellow metal. It is malleable and ductile, and stays shiny in air and water.

30
Q

Iron

A

Iron is a shiny, grey metal. Worldwide, we use more iron than any other metal. Iron is used because when mixed with small amounts of other elements, it’s strong and malleable. It’s also cheap compared to other metals.

31
Q

Physical Properties of Non-Metal

A

Low melting and boiling point, not shiny, brittle.

32
Q

Alloy

A

A mixture of metals, that sometimes include a non-metal element.

33
Q

Material Properties

A

Strength, stiffness, flexibility, brittleness, hardness, conducting heat and electricity, and water absorption.

34
Q

Polymers

A

Polymers are substances that have very long particles. Synthetic polymers include Polyethene, Poly(propene), and PVC. Natural polymers are made by plants and animals, like cotton, silk, wool, and wood.
