3-1 states Of Matter

Question 1

Solid

Answer 1

The state of matter that has a definite shape and volume. It contains closely packed particles that can move slightly (vibrations)

Question 2

Liquid

Answer 2

State of matter that has a definite volume but takes the shape of its container. Particles close together but flow around each other. Move fast enough to overcome some attractions between particles.

Question 3

Surface tension

Answer 3

A force that acts on the particles at the surface of a liquid. It brings water molecules together. Ex: the banana pepper jar

Question 4

Viscosity

Answer 4

a liquid’s resistance to flow. Ex: honey, syrup

Question 5

Gas

Answer 5

The state of matter that has no definite shape or volume.

Question 6

States of matter

Answer 6

The physical forms in which a substance can exist. For example, water commonly exists in three states of matter: solid (ice), liquid (water), and gas (steam).

Question 7

The three most familiar states of matter

Answer 7

The three most familiar states of matter are solid, liquid, and gas.

Question 8

What is matter made of?

Answer 8

All matter is made of tiny particles called atoms and molecules that attract each other and move constantly.

Question 9

Types of solids

Answer 9

Amorphous- not arranged in crystal shape. Ex: rubber, plastic, glass, wax
Crystalline- particles form a regular repeating pattern Ex: salt, ice, snow, iron, diamond. Has a distinct melting point.
