Work Done on a Gas

• What happens to gas particles when they collide with the walls of a container?

  They apply a force at right angles to the walls
• What is the result of compressing gas by applying a force on the piston?

  Work is done on the gas
• How is work defined in physics?

  Transfer of energy by a force
• What happens to the internal energy of 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' energy?

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

  The temperature of the gas increases
• Why do bicycle pumps get warm when used?

  Work is done on the gas, increasing energy
• Where can you find questions on work done on gases?

  In the vision workbook
• What is the relationship between work done on a gas and its internal energy?

  • Work done increases internal energy
  • Internal energy includes kinetic and potential energy
  • Increased internal energy raises gas temperature
• What are the key concepts related to the effect of work on an enclosed gas?

  • Gas particles collide with container walls
  • Work is defined as energy transfer by force
  • Internal energy consists of kinetic and potential energy
  • Temperature relates to average kinetic energy
  • Example: Bicycle pump warms due to work done
