States of matter Flashcards
What are the three states of matter?
- Solids
- Liquids
- Gas
Which state of matter is shown by this particle model?
gas
Which state of matter is shown by this particle model?
Liquid
Which state of matter is shown by this particle model?
Solid
Describe the arrangement and movement of particles in a solid.
- Very close together
- Regularly pattern
- Vibrate on the spot
Describe the arrangement and movement of particles in a liquid.
- Close together
- Randomly arranged
- Move around each other
Describe the arrangement and movement of particles in a gas.
- Far apart
- Randomly arranged
- Move quickly in all directions
Why can’t solids be compressed?
Because their particles are close together and have no space to move into
Why can liquids flow?
Because their particles can move around each other
Why can gases be compressed?
Because their particles are far apart and have space to move into
Which two states of matter cannot be compressed?
Solids and liquids
Which two states of matter can flow?
Liquids and gases
What is the change of state from solid to liquid?
Melting
What is the change of state from liquid to solid?
Freezing
What is the change of state from liquid to gas?
Evaporation or boiling
What is the change of state from gas to liquid?
Condensation
What is the change of state from solid to gas?
Sublimation
What is the change of state from gas to solid?
Deposition
Describe what happens to particles when they melt.
- Energy is transferred to the particles
- The particles move more quickly
- Bonds between the particles are broken
What are the differences between evaporation and boiling?
- In evaporation, particles leave the liquid at the surface only
- In boiling, bubbles of gas form throughout the liquid
- Boiling happens at a specific temperature, whereas evaporation can happen at any temperature
What determines a substance’s melting point and boiling point?
The strength of the forces between the particles in the substance
