Question 1
Igloos (meaning “snowhouses”) is a type of shelter with walls made of blocks of compacted snow. It is built by the Inuit, people who lived in the harsh cold conditions in the Arctic or Greenland, where temperatures can reach as low as -45 °C! Through certain design features, the inside of the igloos can be raised up to 16 °C, just by body heat alone.
(a) Explain how the walls of the igloo can help keep the residents inside warm. [1 point]
(b) The residents normally make a fire inside the igloo so that the inside is warmer. A tourist made a statement that that this will cause the compacted snow walls of the igloo to melt and hence not be effective to keep the residents warm. Comment on whether the tourist is right or wrong, or partly correct. [1 point]
