Surviving the Night in an Igloo: Testing Its Warmth

The video explores an experiment conducted in an igloo to test its insulation properties and the maximum temperature it can reach. Initially, the igloo is comfortable at 2°C, despite the outside being -9°C. The experiment involves raising the temperature using a fondue, reaching a peak of 23°C. The igloo's structure strengthens as the ice melts and refreezes. However, CO2 levels rise, highlighting potential dangers. The experiment concludes that igloos can maintain warmth efficiently, but caution is needed to avoid high CO2 levels.

What was the temperature inside the igloo during the night?

• 2 degrees

• 5 degrees

• 10 degrees

• 0 degrees

What was the purpose of installing thermal sensors in the igloo?

• To measure the humidity

• To monitor the temperature changes

• To detect sound levels

• To check the igloo's structural integrity

What was used to raise the temperature inside the igloo?

• A heater

• A hot water bottle

• A fondue

• A campfire

What was the peak temperature reached inside the igloo?

• 30 degrees

• 15 degrees

• 20 degrees

• 23 degrees

What was the effect of melting and refreezing ice on the igloo?

• It weakened the structure

• It made the igloo more colorful

• It strengthened the structure

• It caused the igloo to collapse

What was the CO2 level inside the igloo after heating?

• Below 0.5%

• Above 0.5%

• No change

• Exactly 0.5%

What is the significance of the cold trench system in the igloo?

• It improves the igloo's appearance

• It provides extra storage space

• It helps maintain a stable temperature

• It increases the igloo's height
