States of matter

Question 1

Solid

Answer 1

Vibrate in a fixed position
Highest density
Fixed volume
Regular arragement
Lowest kinetic energy
Strong forces of attraction to hold the particles close together

Question 2

Liquid

Answer 2

Arranged randomly
The forces of attractions are weaker
Particles move past/around each other
Irregular arrangements
kinetic energy, lower than gas and higher than solid
Move in random directions at slow speed
High density

Question 3

Gas

Answer 3

Arranged randomly
Travel in random directions at high speeds
Particles have the highest kinetic energy
Almost no forces of attraction
Low density

Question 4

Describe physical changes

Answer 4

Do not make new substance
Mass is not conserved
Easily reversible (state changes)

Question 5

What is density add equation

Answer 5

Density is how much mass a substance has per unit of its volume
