Pressure and Temperature in Gases

• Pressure


  The force exerted by gas particles hitting the inside walls of a container
• As temperature increases


  The volume of a gas increases
• As volume increases


  The density of the gas decreases
• As volume decreases


  The pressure of the gas increases
• Gases


  • Gaseous particles are in constant and random motion
  • The pressure that gas creates inside a closed container is produced by the gaseous particles hitting the inside walls of the container
• As temperature increases


  The kinetic energy of each gas particle increases
• As temperature increases


  The gas particles move faster and impact the container walls more frequently
• As volume decreases


  The gas particles hit the container walls more frequently, increasing the pressure
