So how do these houses, made entirely of snow, keep the people inside warm? To retain the heat in the igloo Would you think the same if we told you that beautiful craftsmanship was used?
This is what we usually see on television or in movies. domed snow houses In fact, it is not much different from the houses we live in. In addition, they tried many ways to maintain the temperature inside. Let’s see if physics can explain this situation.
Igloos are known as a warm house in the Arctic areas where cold weather is effective.
If you look at it from a distance, it looks like it will break when you touch it. snow structuresIt can have the warmth to support a family. However, this is not a house built like the snowmen we built.
As we all know, snow has an insulating effect. Special When it snows at night, the environment becomes quieter and the air becomes warmer. This is related to the fact that snow insulates warm air. As in this case, the same logic applies to igloos.
The outer walls of the igloo are covered with fine ice crystals, and these crystals prevent the cold from outside from seeping in.
The hot air inside, gets stuck in the air spaces in the abdomen and these holes retain heat and keep the interior warm. Of course, it should not be overlooked that the number of people and animal skins inside is also very important in maintaining this temperature.
“Then why isn’t the shape square like a house?” you may think. The warmth factor lies behind the domed design. This shape minimizes the effects of wind, maintaining the temperature inside.
When you go in and out, doesn’t the air inside go out and the air outside go in?
No, it’s not possible. Because Access to an igloo is from one point, Neither the cold air can come in nor the warm air out. Do not be confused because the entrance door is not in the same position as the entrance door in our houses.
By digging underground a tunnel is being constructed, While entrances and exits are provided from here, the temperature in the house is also maintained.
You can compare this to a small blanket that keeps us warm while we lie on the couch. Because it retains the warm air and does not make us cold.
Igloos work with a similar logic; The walls prevent evaporation by trapping body heat to maintain the temperature inside. Because it is built with compacted snow, it is compact and… Hardened snow provides a high degree of thermal insulation. The reason is that snow is made up of tiny ice crystals, most of which is semi-frozen water and 95% of which is trapped air.
This air prevents heat loss due to convection effect. The heat escaping from the body interacts with the air inside the igloo. It maintains the temperature of the internal environment.
Cold air is more dense than warm air.
Therefore cold weather to the bottom of the igloo As it settles, warm air moves upward. This minimizes heat loss. A well-constructed igloo can create a temperature difference of approximately 40°C between the inside and outside using body heat.
It is a dome as we know it, but we cannot forget to mention the importance of its shape, which is actually a chain line.
this is special chainline, offers significant benefits when reversed. It provides perfect balance while using minimal material, while effectively supporting its own weight. It is this special shape that ensures that a snow igloo remains firmly in place, even though it has no direct effect on maintaining the temperature.
As you can see, we see it all the time in movies. These warm houses of the Eskimos, It is nothing less than a house shape, just like how we live. The main features that make it a home are its ingeniously designed architecture and its clever use of the rules of physics.
