Is it cold inside and igloo?
Not really. There is a fire in the igloo so it's warm in there.
Why eskimos live in igloo inspite of so cold outside?
An igloo actually holds heat on the inside quite well.
What does the igloo look like inside?
An igloo looks like a round dome made with blocs of ice and snow. There is a ventilation hole in the top igloo so the igloo wont melt because of the fire in it.
How we feel warm in igloo?
It is more like "feel less cold". An igloo is made of blocks of snow. They serve to block wind, and insulate the air inside from the cold outside. If the air outside is -50F, the inside of the igloo might be a nice toasty 10F.
How do people who live in igloo's keep warm?
There is a fire in the igloo that keeps the people living in it warm. The igloo is also made of a few layers of blocs of snow and ice so it can block the wind and cold weather from coming inside.
What principal is used in igloo?
Packed snow is strong compressively but has low tensile strength, so the arched shape converts the weight of the snow into compressive force. The 'doorway' of an igloo is lower than the floor, trapping warm air inside. The packed snow is a very good insulator up to the freezing point, and blocks wind very well, so an igloo stays warm even when it is very cold outside.
What kind of house are in the cold places?
igloo
Where would you have found an igloo?
in the cold areas
How are igloos dangerous?
umm yeah but an igloo is really safe it is not dangerous
How do igloos keep you worm?
The secret to warmth in an igloo is the fact that snow and ice are very good insulators. Apparently what happens is that the inside layer melts, but turns to ice because of the contact with the snow next to it -- so you get good insulation both inside and out. Of course, eventually the igloo would melt, but igloos are typically temporary shelters anyhow, used only for a few days or, at most, weeks. Because the igloo is insulated, it means that the temperature outside the igloo is much colder than inside it, this is mostly to with the fact you are sheltered from the windchill in an igloo.
How long can an igloo last in cold weather?
The temperatures inside an igloo rarely fall below 10-20 °C (50-68 °F). The igloo acts as a windbreak and a form of insulation to the outside temperatures. Energy from inside the igloo (persons body heat) is kept inside the igloo.
How does an igloo become sealed?
After an igloo is constructed out of ice blocks, a fire is lit inside the igloo. This causes the inner layer of ice to melt. When the melted ice refreezes, it seals the igloo.
