Work Done

• Gas inside a piston


  For example, a bicycle pump
• Gas particles colliding with the walls of the container apply a force at right angles to the walls of the container, causing gas pressure
• Compressing the gas by applying a force on the piston


  Carrying out work on the gas
• Work


  The transfer of energy by a force
• Applying a force to the gas

  Transfers energy to the gas particles, increasing the internal energy of the gas
• Internal energy


  Includes both the kinetic energy and the potential energy of the gas particles
• Increasing the kinetic energy of the gas particles


  Increases the temperature of the gas
• Bicycle pump


  • Can get warm when used to inflate a tire
