How Molecules Affect Pressure

1
How Molecules Affect Pressure

• Volume
• Temperature
• Amount of Gas

2
Two Ways Molecules Affect Pressure

• If molecules hit the walls of the container
  harder, pressure goes up.
• If the molecules hit the walls of the container
  more often, pressure goes up.

3
How Volume Affects Pressure at the Molecular Level

• Decreasing the volume means that molecules will
  hit the walls more often, increasing pressure

How temperature Affects Pressure at the Molecular
Level

• Increasing Temperature Increases the Molecules
  Speed
• Molecules hit harder
• Molecules hit more often

5
How the Amount of Gas Affects Pressure

• Adding more gas crowds the molecules, giving them
  less room to move around in.
• Acts like decreasing the volume
• Molecules hit more often, increasing the pressure
