Dewar flask

A vacuum flask or Dewar flask has the remarkable capacity to hold extremely cold liquids like liquid nitrogen for a considerable length of time. The boiling point of liquid nitrogen is 77K compared to a room temperature of about 300K. You can hold liquid nitrogen for about a day without even a cover on the flask! Clearly, the flask is able to effectively block heat transfer from the outside either through the walls or through the open top.
