Guided Notes
3 key concepts
- 1
Gases exert pressure on surfaces, and this pressure increases with more particle collisions, which relates to the kinetic energy of the gas molecules.
- 2
Heating a gas increases the particles' kinetic energy, causing them to move faster and collide more forcefully, thus increasing the pressure; conversely, cooling a gas decreases pressure.
- 3
In a syringe, pulling the plunger increases volume and decreases pressure, creating a vacuum that draws fluid in to repressurize the system to normal atmospheric levels, demonstrating the inverse relationship between volume and pressure.
