KVPY2012PhysicsThermal Properties of Matter

In the Arcitc region hemispherical houses called Igloos are made of ice. It is possible to maintain a temperature inside an Igloo as high as 20^ C because-

Options

  1. AIce has high thermal conductivity
  2. BIce has low thermal conductivity
  3. CIce has high specific heat
  4. DIce has higher density than water

Correct answer

B. Ice has low thermal conductivity

Step-by-step solution

Ice has low thermal conductivity So no exchange of heat outside surrounding.
