Work Done on a Gas (T)

• How do gas particles create pressure in a container?

  By colliding with the walls of the container
• What happens when you compress gas by applying force on the piston?

  You carry out work on the gas
• How is work defined in the context of physics?

  As the transfer of energy by a force
• What happens to the internal energy of the gas when work is done on it?

  It increases
• What does the internal energy of a gas include?

  Kinetic energy and potential energy of particles
• How is the temperature of a gas related to its particles?

  It is related to the average kinetic energy
• What happens to the temperature of the gas when its kinetic energy increases?

  The temperature of the gas increases
• Why do bicycle pumps get warm during use?

  Because work is done on the gas
• What are the effects of doing work on an enclosed gas?

  • Increases internal energy
  • Increases kinetic energy
  • Increases temperature
• What is the relationship between work done on a gas and its temperature?

  • Work done increases internal energy
  • Increased internal energy raises kinetic energy
  • Higher kinetic energy results in higher temperature
