Lab 1: The latent heat of vaporization of liquid nitrogen

  • Supervisor:Dr. Yongkang Le
  • Location: Room 201-207, Henglong Physics Building
  1. Review the physical concepts and relationships associated with the flow of heat into and out of materials.
  2. Determine the latent heat of liquid nitrogen (LN).
  • Heat transfer
  • Specific heat
  • Latent heat
  1. Electric thermometers
  2. copper cylinder
  3. Water
  4. Warm isolated cup
  5. Stop watch
  6. Electric balance
  7. Liquid nitrogen

  1. Calculate the total heat energy transferred to liquid nitrogen by the copper cylinder.
  2. Get the your measured value of the latent heat of LN.
  1. List various factors,especially errors in measurement and experimental work,which might affect your measured value.
  2. What have you learned from this lab?
