HOW IGLOOS KEEP US WARM

HOW IGLOOS KEEP US WARM?

HELLO DEAR FRIENDS, IN THIS POST WE WILL BE DISCUSSING THAT "HOW DO IGLOOS KEEP US WARM IN HARSH CLIMATIC CONDITIONS OF POLAR REGIONS EVEN THOUGH THEY ARE MADE UP OF COOL SNOW"

SO, LET'S BEGIN,

WHY WE FEEL COLD?

DID YOU EVER THOUGHT WHAT IS "COLD"? COLD IS NOTHING BUT, LOSE OF HEAT...

THE MORE YOU LOSE HEAT, MORE YOU WILL FEEL THE COLD...

OUR SWEATERS AND BLANKETS DOES NOT PROVIDE ANY HEAT TO US, INSTEAD, IT JUST PREVENTS THE BODY HEAT TO ESCAPE INTO THE ENVIRONMENT AND THUS KEEPING US WARM...

WHAT IS AN "IGLOO" MADE UP OF?

AN "IGLOO" IS MADE UP OF A KIND OF SNOW HAVING

BOTH DENSITY AND STABILITY SO THAT IT COULD BE FORMED INTO AN IGLOO AS WELL AS FACE THE ICY COLD WINDS OF POLAR REGIONS. THERE ARE MANY TYPES OF SNOWS WHICH DECIDES

THAT WILL IGLOO PROVIDE WARMTH (COZINESS) OR NOT.

HOW AN "IGLOO" KEEPS US WARM??

WE ALL KNOW THAT IGLOOS ARE MADE UP OF ICY COLD SNOW, BUT STILL IGLOOS KEEP US WARM, THIS IS THE SAME PHENOMENA THAT HAPPENS WHEN WE WEAR SWEATERS OR LAY INSIDE A BLANKET... I.E; "THE INSULATION OF THE BODY HEAT".

AN IGLOO IS MADE OF SNOW WHICH HAS PACKED AIR MOLECULES, MAKING IT AVERY GOOD INSULATOR...

AN IGLOO IS DIVIDED INTO CHAMBER (UPPER) AND (LOWER)

THE WARM AIR INSIDE DUE TO "RADIATION" OF BODY HEAT GETS TRAPPED INTO THE UPPER CHAMBER, WHERE ONE CAN LIVE.

AND THE COLD AIR REMAINS AT THE BOTTOM CHAMBER/LEVEL.

A THIN LAYER GETS DEVELOPED AS AN INNER LINING OF THE IGLOO MAKING A BARRIER BETWEEN THE SNOW AND THE INTERNAL ATMOSPHERE...

AN IGLOO CAN MAINTAIN A TEMPERATURE OF ABOUT 40-60 DEGREES CENTIGRADE "MORE THAN THAT OF THE EXTERNAL ATMOSPHERE"... THIS MAKES IT ENORMOUSLY USEFUL IN HARSH CLIMATIC CONDITIONS.
