how does a gas exert a pressure

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
