Kinetic Particle Theory Flashcards
what is matter?
anything that has mass and takes up space
what are the 3 states of matter?
- solid
- liquid
- gas
what is the movement of solid?
vibrating about in fixed places
what is the movement of liquid?
free to move/sliding past one another
what is the movement of gas?
moving freely in all directions at great speeds
what is the spacing of solid?
very close together
what is the spacing of liquid?
close together
what is the spacing of gas?
far apart
what is the order of solid?
orderly
what is the order of liquid?
disorderly
what is the order of gas?
random
what is the energy of solid?
least
what is the energy of liquid?
> solid
what is the energy of gas?
most
what is the forces of attraction of solid?
very strong
what is the forces of attraction of liquid?
strong
what is the forces of attraction of gas?
weak
which states have fixed volumes?
- solid
- liquid
which states have fixed shapes?
solid
which states can be compressed?
gas
which states can flow?
- liquid
- gas
what is kinetic particle theory?
- particles are too small to be seen
- there are spaces between the particles of matter but the amount of space is different between the different states
- the particles of matter are in constant motion and their particles in different states move at different speeds
what is the process of solid to liquid?
melting
what is the process of liquid to solid?
freezing
what is the process of liquid to gas?
- boiling
- evaporation (without boiling)
what is the process of gas to liquid?
condensation
what is the process of solid to gas?
sublimation
what is the process of gas to solid?
condensation
what is the meaning of volatile?
low boiling point, close to room temperature
how to answer kinetic particle theory questions?
- process
- gain/lose energy
- change movement
- change arrangement and spacing
