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amount of energy, has a certain temperature when power is supplied to the body, the temperature rises, when energy is withdrawn, the temperature drops.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 But even in that state, water molecules keeps some movement, and of course even vibrate, this because they are not withdrawn all the energy they possess.

How is called the popcorn in Latin American countries?

This delicious meal is known by many names according to the country, even to the region, and it is interesting to note that the names used for popcorn almost are not repeated from country to country, but practically in all countries recognize the name in English (Popcorn), probably because this is the name used in the movies and television.

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)
