How ice works as a heat insulator

We all know the three water conditions: liquid, gas and solid, and the presence of water in the physical state of these three cases depends on the temperature of the medium in which the water is located. If the temperature is more than one degree Celsius and less than 100 degrees Celsius, The water is in the liquid state, and if the temperature reaches 100 ° C, the water will start to boil and turn to steam; it is the gaseous state of the water. If the temperature is zero or less than zero, the water will freeze and turn into ice or ice. The solid state of water is the subject of our conversation in this article.

Ice is the symbol of purity, serenity, purity and chastity, for its pure white color, which sends serenity and purity in our hearts. Snow is also a symbol of the slow and cruel death of its intensity and intensity.

Snow is also one of the forms of precipitation we see in the cold winter, and is in the form of ice crystals accurate, so increase its density and abundance as we move towards the poles of the North and South, but not in all countries.

As you know that the poles of the earth is composed mainly of snow, so we notice that the people of Eskimo build houses of snow, although the temperature is low but it is suitable for building houses in those areas, because of its great ability to isolate the heat, thermal insulation materials that we use In the walls of the building is very important, and the more efficient it reduced the need to use energy sources, but the houses of the people of the Eskimos built of ice, as they do not use any material to isolate the heat, the snow alone the ability to isolate the heat.

Although the temperature of the snow is very low, but it has the ability to prevent cold outside air from entering those houses and also raise the degree of the house, if we assume that the temperature outside was within the limits of 50 below zero, the temperature inside the house built Of the ice will be about 50 degrees Celsius.

But how does snow isolate heat ? When the water freezes, the spaces between the particles are reduced. The lower the spaces, the greater the outside air from entering, and the trapped bubbles inside the snow act as heat insulating material.
