Matter Flashcards
What does “classifying” mean?
To place things in groups based on their common properties.
What is “matter”
The substance that every substance is made of.
What are the 3 states of matter?
What is “particle theory” ?
Using the arrangement of particles in solids liquids and gases to explain their properties
Which state of matter is shown?
A solid
Which state of matter is shown?
A liquid
Which state of matter is shown?

A gas
What are 6 properties of solids?
What are 6 properties of gases?
What are 6 properties of liquids?
What does “flow” mean?
The ability of particles to move around one another.
What is compression?
Using force to squeeze the same number of particles into a smaller volume.
Why can’t solids and liquids be easily compressed?
Beacuse the particles are already very closely packed together
What is density (S1)?
number of particles
area
Place the 3 states in order of density starting with most dense.
- solids
- liquids
- gases
Which experiment shows that liquids have spaces?
Water and alcohol mixing
What is diffusion?
The particles of one substance moving through the particles of another
In which state does diffusion happen most quickly?
Gas
What was diffusion in liquids experiment
What was diffusion in gases experiment?
Plaace the 3 states in order of diffusion speed.
- gases
- liquids
- solids
What is needed for diffusion to happen in matter?
- Particles moving
- Spaces for particles to move into
What is expansion?
Same number of particles with an increse in volume
What is contraction?
Same number of particles with a decrease in volume
