How Bonding and Structure are related to the Properties of Substances Flashcards
1
Q
Name the three states of matter
A
- Solid
- Liquid
- Gas
2
Q
What changes of state occur at the melting point of a substance?
A
Melting (solid to liquid)
Freezing (liquid to solid)
3
Q
Which changes of state occur at boiling point of a substance?
A
Boiling (liquid to gas)
Condensing (gas to liquid)
4
Q
Explain why solids are hard to compress using particle theory
A
Particles in solids are packed together
These particles vibrate in fixed positions and there are no spaces between the particles
They have a fixed volume
5
Q
Explain why solids have a fixed shape and cannot flow using particle theory
A
The particles can vibrate but they cannot flow freely over eachother
6
Q
Explain why liquids are difficult too compress using particle theory
A
The particles in liquids do not have many spaces between them
