(11 cards)
What are the 4 properties of particles in a solid?
- Particles are very close together
- Arranged in a regular pattern
- Vibrate around a fixed position
- Low energy
What are the 4 properties of particles in a liquid?
- Particles are close together
- Particles are randomly arranged
- Particles move around each other
- Greater energy than a solid
What are the 4 properties of particles in a gas?
- Particles are far apart
- Particles are randomly arranged
- Particles move quickly in all directions
- Highest energy of all 3 states
What are the properties of a solid substance?
- Solids have a fixed shape
- Particles cannot flow as they can’t move from place to place
- Cannot be compressed as the particles are close together and have no space to move into
What are the properties of a liquid substance?
- The particles flow and take the shape of their container, as they can move around each other
- Can’t be compressed as the particles are close together and have no space to move into
What are the properties of a gaseous substance?
- Flow and completely fill their container because the particles can move quickly in all directions
- Can be compressed as the particles are far apart and have space to move into
How can a change of state occur?
Energy must be transferred, by heating, to a substance for it to change state
What effects the amount of energy needed to undergo a change of state?
The strength of the intermolecular forces between the particles
If the melting point is above the given temperature, what is the state of the substance?
Solid
If the given temperature is between the melting and boiling points, what is the state?
Liquid
If the given temperature is above the boiling point, what is the state of the substance?
Gas
