What is called absolute zero?

The temperature of a body, is the measure of the energy the body has stored, like this when a body has stored a certain amount of energy, has a certain temperature when power is supplied to the body, the temperature rises, when energy is withdrawn, the temperature drops.

At different levels of temperature (ie energy), molecules of the body are moving at speeds proportional to the level of energy, so that, for example, when the water heats, its molecules moving increasingly fast, at some point (boiling point), the molecules tend to separate because its moving is fast, and therefore the water changes phase and is turn into vapor.

Instead, when you go removing energy (cools) of the body the molecules are moving ever more slowly, in the example of water, when we cooled, the molecules begin to lose energy (kinetic energy, ) and when you reach a certain point, the water begins to solidify, this because the molecules have so few kinetic energy, that can not overcome the intermolecular attractive forces, and begin to form crystal lattices, so ice crystals form . But even in that state, water molecules keeps some movement, and of course even vibrate, this because they are not withdrawn all the energy they possess.

What does mean the value of the Dow Jones index?

To begin, we must mention that the index that is generally known as the "Dow Jones index" actually refers to only one of the indices of the group called "Dow Jones Stock Index."

The specific index that is broadcast is usually the "Dow Jones Industrial Average" (DJIA), and is the most important group of Dow Jones stock index.

The DJIA is the oldest index in the United States along with the Dow Jones Transportation Average.

What says the DJIA, is the average share prices of the 30 largest companies in the United States. (Note that the word "Industrial", led him initially, because the 30 largest companies were industrial, but today, some computer companies and some financial institutions have exceeded the firsts, but the denominative is maintained)

Why the dogs pant?

The reason why these faithful animals pant, is that they do not have sweat glands.

Warm-blooded animals (including humans), has these glands in order to lose body heat when it rises. In the moment the body begins to heat up, the sweat glands cover certain areas of the skin with a thin coat of liquid (mostly water), which while it evaporates, cools the skin (the water in order to evaporate, requires a certain amount of energy, in this case the heat of body, that is transfered through the skin), then, the skin extracting heat in this process.

Therefore, because the dogs not have sweat glands, have another mechanism to cool their bodies, they are cooled, carrying a large amount of blood into the tongue, Then when the dog gasps, passed cold air over the surface of its tongue, the heat exchange that takes place, causes the blood passing through the tongue to cool, and it, when returns to the animal's body in its normal circulation, it cools. Because the tongue is also wet, when the moisture evaporates, remove even more heat.

The wisdom of nature gives each species the mechanisms to overcome obstacles every day.

Welcome message

On this blog you will be finding answers to interesting questions about science, technology and much more.

I Will try to make the answers to those questions are as close to reality and when I will make a mistake, this will be corrected in the shortest time possible. Also I will avoid response to questions on political, religious and to a certain exent philosophical topics, because I am convinced that in such topics, "the only absolute truth, is there is no absolute truth"
