solids, liquids and gases Flashcards
1
Q
solids have:
A
A definite shape (they are rigid)
A definite volume
2
Q
particles in solid are:
A
The particles are closely packed
The particles vibrate about fixed positions
3
Q
Liquids have:
A
no fixed shape (take up of container)
a definite volume
4
Q
particles in liquid are:
A
The particles are closely packed
The particles can flow over one another
5
Q
Gases have:
A
No definite shape – they will take the shape of their container
No fixed volume – if placed in an evacuated container they will expand to fill the container
6
Q
particles in gas are:
A
The particles are far apart
The particles move randomly
7
Q
why are gases highly compressible?
A
There are large gaps between the particles
It is easier to push the particles closer together than in solids or liquids
