P3-particle Model Of Matter Flashcards
1
Q
What are the characteristics of a solid
A
Strong forces of attraction
Fixed,regular arrangement
Vibrate
Density is highest
2
Q
What are the characteristics of liquids
A
Weaker forces of attraction
Close together, but can move past each other
Move in random directions at low speeds
Less dense than solids
Irregular arrangement
3
Q
What are the characteristics of gases
A
Almost no forces of attraction
Free to move
Travel in random directions and high speeds
Low densities
4
