equation for pressure
pressure = force/area
properties of particles in a gas
spaced out,
random,
collide with container but not with each other,
exert a force on container
what is a force
a push or pull
factors that affect pressure
amount of gas
temperature
volume of container
how does increasing the amount of gas affect pressure
increases number of particles.
more particles -> more collisions -> more force -> more pressure
how does increasing the temperature of gas affect pressure
increases speed of particles
more collisions -> more force -> more pressure
how does increasing the size/volume of container affect pressure
decreases density -> fewer collisions per second -> less force -> less pressure
