P3 Fsl Flashcards
Tell me the particle arrangement in a solid
•The particles are very close together
•Particles are arranged in a regular pattern
•particles vibrate but do not move from place to place
What is the particle arrangement in a liquid
•Particles are close together
•Particles are not arranged in a regular pattern
•Particles can move around each other
What is the particle arrangement in a gas
Particles are very far apart
Particles are not arranged
Particles move very rapidly
What does the density of a material tell us
It tells us the mass of a given volume
Which has more density brick or block of polystyrene
Brick
Why do bricks have high density
It has lots of mass packed in its volume
Why do polystyrene blocks have low density
It has low mass packed into its volume and full of air spaces
How do you calculate density
P=m/v
Why do solids usually have a high density
Because particles are packed together and they have a lot of mass in their volume
Do liquids have a high density and why
Yes. Because the particles are close together and they have a lot of mass in their volume
Why do gases have a low density
The particles are far apart so gases only have a small mass for their volume
Why does
