movement of particles Flashcards
why are solids hard to compress
the distance between the particles ar very small and have very high density
what is the distance like between particles in liquids
there is a smal distance so particles have high density
what is the distance like between particles in gases
there is a very large distance between particles so they have low density
what is the particle motion like in a solid
they only vibrate so they cant flow
what is the particle motion like in a liquid
slow so they can flow
what is the particle motion like in gases
fast so they can flow
what is the brownian motion
the random movement of any particle floating in a liquid or gas
what is movement like in brownian motion
random, zigzag motion or large particles
what causes a change in direction in brownian motion
collisions
what is diffusion
the spreading out of particles from higher to lower concentration caused by their random motion
when there is a higher temperature what happens to particles movement
particles move faster
what happens to the space between particles when there is a higher temprature
spaces between particles increase
what is an example of how particles change when heated
when the liquid in a thermometer is heated it expands further up the tube
if you heat a substance enough what will happen
it will change state
