How Igloos Turn Snow into Toasty Havens

The video explores how igloos, made of snow and ice, provide warmth in Arctic conditions. It explains the principles of heat transfer: conduction, convection, and radiation. Igloos act as insulators, trapping body heat to maintain a warm interior. The design of igloos, with terraces, optimizes heat distribution. The video highlights the ingenuity of the Inuit people in creating such effective shelters without formal knowledge of physics.

What is the primary way heat is transferred in fluids?

• Evaporation

• Radiation

• Convection

• Conduction

How does an igloo help in retaining body heat?

• By reflecting sunlight

• By generating its own heat

• By allowing heat to escape

• By acting as an insulator

What material property of snow makes it a good insulator in igloos?

• Its weight

• Its color

• Its density

• Its air content

Why is the igloo floor designed with terraces?

• To create more space

• To make it aesthetically pleasing

• To separate living areas

• To manage heat distribution

What is the temperature difference an igloo can create between its interior and the outside environment?

• 20°C

• 30°C

• 40°C

• 10°C
