However, the human body has a serious coffee cup heater problem that the body is active at any time

Water is a substance or material or element that is essential for all known forms of life on earth to date, but not on another planet. Water covers nearly 71% of the earth's surface. Water can be either solid (ice), liquid (water) and gas (water vapor). Water is the only substance which is naturally present in the earth's surface in the third his form.
Approximately 70% of the human body consists of water. Body cells contain various substances but none as much or as important as water. The largest part of the blood that circulates in any place within the human body of course water. But this does not only apply to human beings themselves or anyone else: most of the bodies of all living things is water. Without water life can not exist.
In the cell (the cell membrane) water is used as solvent moves from a solution of lower concentration (hypotonic) to the more concentrated solution tinggai (hypertonic) which aims to equalize the concentration of the two solutions. This effect can be seen from the increasing pressure on the hypertonic solution relative to the hypotonic solution. So that the osmotic pressure is defined as the pressure required to maintain equilibrium, in the absence of solvent flow. Osmotic pressure coffee cup heater is a colligative property, which is property that gayut the molar concentration coffee cup heater of the solute and not on the type of substance.
6. Water has a high surface coffee cup heater tension enough so that the water will be lifted to the surface substances. As a result: these substances more easily transported / disposed / digested by enzymes.
8. Water as a catalyst or components that simplify and accelerate a variety of biological reactions in the body, including the digestive tract. Water is also needed to break down and hydrolyze the complex nutrients into simpler forms.
1) All known solids will shrink if it gets colder. It also occurs in all known liquids: When the temperature decreases, the liquid volume loss. When the volume decreases, the frequency increases coffee cup heater so that the cooler part of the liquid that becomes more severe. According to the normal laws of physics, solid water, called ice, ought to be heavier than liquid water, and should be drowned when the ice; however coffee cup heater it turns out, the ice floats.
2) When ice melts or water evaporates, ice or water absorbs heat from its surroundings. coffee cup heater When the transition is reversed (ie when water is frozen or vapor condenses, heat is released. In physics the term "latent heat (latent heat)" is used to describe the heat released. All liquids have a latent heat as it is, but the water was among liquid has the highest latent heat. At temperatures "normal", the only liquid with higher latent heat of water when it freezes is ammonia. On the other hand, in relation to the nature of the latent heat of condensation, no liquid can offset water. coffee cup heater
One phenomenon of the role of water in the human body is sweating. All mammals have the same relative body temperature. Although it varies, it is not too flashy and mammalian body temperature ranges between 35 - 40 C. The temperature of the human body is about 37 C under normal conditions. This temperature is the critical temperature and must be kept to an absolute constant. If the human body temperature decreased by only a few degrees, many vital body functions will fail. If the body temperature rises even though only a few degrees, as happens when a sick man, the effect can be devastating. Body temperature to stay above 40 C can lead to death. In short, we have a balance of body temperature is very critical and does not allow for variation.
However, the human body has a serious coffee cup heater problem that the body is active at any time. All physical motion, such as motion machines, require the production of energy to remain active. But whenever energy coffee cup heater is generated, coffee cup heater heat is always released as a byproduct. But the fact is, if people realize, man did not become as hot as it should be.
Therm is calories. A normal person who ran 10 miles in one hour will produce around 1,000 calories of heat. Heat must be removed from the body. If not, people will pass out into a coma before completing the first kilometer. But the danger avoided by a third thermal properties of water.
To keep the body cool to the heat generated, the body uses sweat mechanism. When humans sweat, water spreads on the surface of the skin and quickly evaporates. But due to the latent heat of water is very large, the evaporation requires heat that great anyway. Heat is of course taken from the body so it stays cool. This cooling process is so effective that terkada
