Topic 3 Density Of Materials

Question 1

Solid

Answer 1

Strong forces of attraction join the particles close together in fixed regular arrangement
Vibrate about the fixed position
The density is generally highest in this state as the particles are closest together

Question 2

Liquid

Answer 2

Weaker forces of attraction
Patidels are close together but can move past each other and form irregular arrangements
They have more energy than solids and move in random directions at low speeds
Less dense then solids

Question 3

Gases

Answer 3

Almost no forces of attraction between the particles
The particles have more energy than in liquid and solids
Free to move and travel in random directions at high speeds
Generally have low densities

Question 4

What is a dense material

Answer 4

Has its particles packed tightly together
More mass in a given volume

Question 5

What would happen if you compressed a material

Answer 5

Particles would move closer together and become more dense
