Matter Flashcards
PHYSCI8 - Matter
Matter
Anything that has mass
Elements
Only has one type of atom
- Elemental Gold > only Gold atoms
- Elemental copper > only Copper atoms
Four characteristics of Matter
- Tiny particles
- Spaces in between atoms
- Particles are always moving or has kinetic energy
- Particles of matter attract eachother
Three states of Matter
Solid, Liquid, Gas
Solid
definite shape and definite volume
Motion of Solid
particles vibrate in all directions
Liquid
no definite shape; takes the shape of its container and definite volume
Motion of Liquid
particles free to move past neighboring particles
Gas
no definite shape and no definite volume
Motion of Gas
particles move freely
Attraction of Solid
strong attraction
Attraction of Liquid
weaker attraction than solid
Attraction of Gas
less to none attraction
Which state/s of matter cannot be compressed further
Solid
Which state/s of matter can be compressed
Gas and Liquid
- They can be compressed due to the spaces in between particles
What causes particles in the states of Matter to continuously move
Kinetic energy
Particles of _____ can move much faster than solid particles and can slide past each other
Liquid
What is the underlying force responsible for the interaction between particles of matter?
Attraction
______ has almost no to less attraction
Gas
Which state has the most kinetic energy?
Gas
Which state has the most amount of attraction?
Solids
Kinetic Particle Theory of Matter
- all matter is made up of tiny particles
- particles attract each other
- each pure substance has its own kind of particles
- particles have more energy in hotter temperatures and less in lower temperatures
Particles move ______ in higher temperatures and ______ in lower temperatures
- faster
- slower
Solid to Liquid
Melting
- particles gain energy
Liquid to Gas
Evaporation
- particles gain energy
Gas to Liquid
Condensation
- particles lose energy
Liquid to Solid
Solidification
- particles lose energy
Gas to Solid
Deposition
- no liquid phase
Solid to Gas
Sublimation
- no liquid phase
Characteristics of Matter
Mass and Volume
Volume
Amount of space matter occupies
Mass
Amount of matter in an object
