Shape

Answer 3

solids liquids gases
fixed/regular
shape takes the shape takes the
of part the container shape of
it is in the entire
container it is in

Question 4

Volume

Answer 4

solids- volume is fixed
liquids- volume is fixed
gases- variable- it expands to fill the container it is in

Question 5

Density

Answer 5

solids-usually high
liquids- usually lower than those in solids
gases- low

Question 6

Compressibility

Answer 6

solids-cannot be compressed
liquids- may be compressed very slightly by applying high pressure
gases-very easy to compress

Question 7

Arrangement of particles

Answer 7

solids-packed closely together, in a regular way
liquids-have small spaces between the particles and are randomly arranged
gases-have large spaces between the particles which are randomly arranged

Question 8

Forces of attraction between the particles

Answer 8

solids-strong
liquids-weaker than those particles in a solid
gases- very weak

Question 9

Kinetic energy

Answer 9

solids-possesses very small amounts of kinetic energy
liquids-has more kinetic energy than the particles in a solid
gases-possesses large amounts of kinetic energy
