particle motion and pressure in gases. Flashcards
the hotter a material the more/less energy its particles have?
more.
in a solid the particles …….. faster?
vibrate.
in fluids (liquids or gases) they …… faster?
move.
molecules of a gas are in what type of motion?
constant random.
temperature of the gas is related to the what energy of the molecules?
average kinetic energy.
what don’t gases have?
definite shape or volume.
what do gases always do?
expand to fill the shape of any container.
what is gas pressure due to?
particles colliding with a surface.
what happens if you remove some of the particles of a gas from a container in terms of gas pressure and particles at a what?
fewer particles to collide with the walls of the container and the pressure decreases at a given temperature.
what angle do the collisions of gas particles happen at in a container, what are these called and what don’t they do?
90.
elastic collisions.
don’t loose energy.
as the temperature inside a sealed container increases how do the particles move?
faster.
collisions with the walls of the container have what kind of frequency and what kind of force do they involve?
more.
larger.
if the collisions inside a container containing gas particles what happens to the pressure inside the container?
increases.
