• The temperature, pressure and the volume of gas can affect each other

  
  

• Laws Of Temperature

  • Boyle’s Law (Pressure ↔ Volume)

  • Charles’ Law (Volume ↔ Temperature)

  • Gay-Lussac’s Law (Pressure ↔ Temperature)

  • The pressure of a gas is caused by atoms or molecules

    hitting the walls

• More heat → more energy → faster movement

• Less heat → slower motion → lower temperature

Boyle Law

• When you squeeze a gas (increase pressure), it takes up less space (volume) but the temperature stays the same

• Pressure x Volume = Constant

• Breathing – Chest expands, lungs get more space, pressure drops, air comes in.

• initial pressure x initial volume = final pressure x final volume

Inversely Proportional

• two quantities are inversely proportional when increasing one quantity decreases
