Density Flashcards
density equation
density=mass/volume
/__M__\
/P|V\
the density of water
1g/cm3
if an object has a density less that water it will
float
if an object has a density more than the density of water it will
sink
Kinetic theory
the theory that explains the structure and behaviour if solids, liquids and gases
kinetic theory states that
- all matter is made up of tiny, invisible moving particles
- the particles are continually moving and if the temperature is raised the particles gain energy and move more quickly
- at a given temperature lighter particles move more quickly than heavier ones do
solids shape
stay the same shape
solids volume
stay the same volume
solids volume
stay the same volume
solids density
high density
liquids shape
flow easily. takes the shape of their container
liquids volume
stays the same volume
liquids density
medium density
gases shape
flow easily. takes the shape of their container
gases shape
flow easily. takes the shape of their container
gases shape
flow easily. takes the shape of their container
gases volume
expand to fill all available space
gases density
low density
Brownian motion
gas particles must be moving
1. randomly
2. at high speed
