6-3 Understanding Gas Behavior
Understanding Gas Behavior
Gases behave differently than solids
changes affect gases more than solids/liquids
changes in temperature
changes in volume
Kinetic molecular theory is an explanation of how particles in matter behave
small particles make up all matter
these particles have constant motion
when particles collide no energy is lost
Pressure
pressure is the amount of force applied per unit of area
when volume decreases, pressure increases
smaller container means gas particles collide with container more frequently
Pressure and Volume
particles colliding with a container causes pressure
Boyle's Law
pressure of a gas increases if the volume decreases and the pressure of a gas decreases if the volume increases when temperature is constant
TL;DR:
more volume = less pressure, less volume = more pressure, but only when temp is constant
In Action
in eardrum on plane
air outside loses pressure
air inside keeps constant pressure
air inside ear increases volume
Graphing
curved, downward-sloping graph
Temperature and Volume
changing temperature of gas can change its behavior
Charles's law
volume of gas increases with increasing temperature
in action
balloon changes size when it gets cold.
