Nobody seems to know accurately when the first coffee was taken there (or in any part of this country. They ate or they chewed. On the basis of registers that they look to unmask the myth and to know the reality on the history of the consumption and expansion of this drink. It demonstrates that it was led stops far from its native land in middle of century XV, parallel to the European maritime expansion. Arriving in the Imen, before it belonged to the Arab Empire therefore having confusion. It has studies that it demonstrates that they had been the Persians who had led? in the one for the Etipia in the VId.c century period where they had invaded this country. When arriving in the Imem, the Arabs had been the first ones to cultivate the coffee, therefore the scientific name of the plant is Arabian Coffea – scientific name of one of the most important species of the coffee.
The Arabs who had introduced the custom that ocidente preserved the custom to drink the coffee – instead of eating or chewing, as the pioneers. Later, in Africa, another species of coffee was developed, also with its types and characteristics, ' ' Robust Africana' ' , known in Brazil as ' ' Conillon' ' , where less it is consumed than the Arabic. The coffee was brought of the French Guyana to Brazil, for the sergeant-mor Francisco de Melo Vane. It did not obtain the changes in planned way asking for to the governor of the French Guyana, but to if becoming loving of it obtains it to the son by means of a gift of fired, enters the flowers dissimulated for the foliage if it found changes of seeds, thus in this gift find the embryo of the national empire. Of Par, if it extended for the Maranho, finally in 1760 was brought for Rio De Janeiro for Alberto Joo Castello Branco, where if it spread for the Of the state of Rio de Janeiro, South Lowered one of Mines, Espirito Santo and later for the Valley of the Paraba reaching later Campinas, in the old West of So Paulo later New West the region where if it finds Ribeiro Preto and Araraquara and it passed later to the purple land regions of the North of the Paran and Mato Grosso.
Thermodynamics? Basic concepts Therme (heat) and dynamis (force), words Greeks who in its junction had given to origin the thermodynamic word, that appeared with the attempt to transform heat into work, being its study the main objective of this science. If arresting only to this concept this science currently it does not approach all the energy forms and its transformation, thus, we can say that the thermodynamics is the science that studies the energy in its diverse forms. The First one I begin of the Thermodynamics establishes that any interaction enters the substances the contained energy in one can changed into any the other more total amount is remained constant, that is, the energy is not created and nor if it only destroys we can transform it, is carrying about one of the basic laws of the nature, also known as law of the Conservation of Energy. As I begin of the Thermodynamics affirms that nor all the transformations where the energy if conserve can occur. Classic thermodynamics is study that approaches the substance in a generalista way if not worrying about the behavior of particles.
