P3 Flashcards
Give 4 properties of solids.
- have a fixed regular arrangement
- all particles are touching
- vibrate in a fixed position
- have string intermolecular forces of attraction
Give 3 properties of liquids.
- have a random structure
- all particles are touching
- the particles can move
Give 3 properties of gases>
- have a random structure
- the particles do not touch
- have weak inter- molecular forces of attraction
what forces of attraction is in a solid?
strong intermolecular forces of attraction
what forces of attraction is in a liquid?
what forces of attraction are in a gas?
weak intermolecular forces of attraction
do solid have a high or low density? why?
high density
- because the particles are arranged close together
can solids flow? why?
no because the particles are in a fixed position
are solids compressible or incompressable why?
incompressable - because the particles are touching and there are no gaps in between
do liquids have a high or low density? why?
high density
- because the particles are arranged close together
can liquids flow? why?
yes - because they have a weaker intermolecular force of attraction so their particles can move
are liquids compressible or incompressible? why?
incompressible - because the particles are touching so little gaps in between
do gases have a high or low density?
low density - because the particles are spaced out and occupy a large volume
can gases flow?
yes - because they have weak intermolecular forces of attraction
what are 4 limitations of the particle model?
- doesn’t show the motion of the particles
- the model is 2D but states of matter are 3D
- drawn as spheres but that’s not how they actually look
- doesn’t show the forces of attraction between the particles
what is the definition of denisty?
the mass per unit volume
what sate of matter is the most dense?
solids
what is the definition of resolution?
the smallest change in a quantity that will result in the change in the measurement being taken
