scales of a thermometer (human heat)

high heat-38-......

thermometer:instrument used to measure the temperature.the most used thermometer is the made up of mercury,formed by a capillary of glass of a uniform diameter comunicated by an end with a bladder full with mercury.

types of thermometer:
*made of glass and using mercury.
*made of glass and using niquel oxid, cobalt and magnesium.
*for high temperatures:made of metal using electronic circuits.

1.The thermometer is an instrument for measuring temperature. Since its invention has evolved greatly, especially since it was started to manufacture digital electronic thermometers. Initial thermometers were manufactured based on the principle of expansion, it is preferred to use materials with a high coefficient of expansion so that, with increasing temperature, dilation of the material is easily visible. The base metal that was used in this type of mercury thermometers has been locked in a glass tube incorpo.

The scale used in most countries is the centigrade (º C), also called Celsius since 1948, in honor of Anders Celsius (1701 to 1744). On this scale, zero (0 º C) and one hundred (100 º C) degrees correspond to the freezing point and boiling point of water, both at 1 atmosphere pressure. Other thermometer scales are: Fahrenheit (º F), proposed by Gabriel Fahrenheit in 1724 [citation needed], which is the unit of temperature in the English system of units, used mainly in United States. Réaumur degree (º R), into disuse. Is due to René-Antoine Ferchault of Reamur (1683-1757). The relationship with the Celsius scale is TReamur = (4 / 5) * TCelsius Kelvin (K) and absolute temperature, temperature unit in the International System of Units. Its zero is unattainable by definition and is equivalent to -273.15 ° C.rating a graduated scale.

2.There is no firm agreement amongst neurologists as to exactly how many senses there are. The disagreements stem from a lack of consensus as to what the definition of a sense should be. Although school children are still routinely taught that there are five senses (sight, hearing, touch, smell, taste; a classification first devised by Aristotle), it is generally agreed that there are at least nine different senses in humans, and a minimum of two more observed in other organisms.

The skin is the outer covering of the body. In humans, it is the largest organ of the integumentary system made up of multiple layers of epithelial tissues, and guards the underlying muscles, bones, ligaments and internal organs.[1] Skin of a different nature exists in amphibians, reptiles, birds.[2Human skin is not unlike that of most other mammals except that it is not protected by a pelt and appears hairless though in fact nearly all human skin is covered with hair follicles.


4.In the city of Bangalore, India, the main annual festival of the Karaga draws its ritual personnel from a network of wrestling houses, where concepts of the conservation and channeling of bodily fluids underlie training. These concepts are, in turn, linked to an older model of urban planning in which artificial water bodies and gardening were integral components of the built environment. As the city’s population has grown and its economy shifted toward manufacturing and high technology, a different model of planning has slowly destroyed the older ecological system while inserting large sports complexes as important urban nodes. There is a simultaneous movement to link sports, beauty contests, and media as entertainment, with a concomitant redefinition of the body.

5.The body's enzymatic processes slow over 10%, sometimes 20% per degree of temperature below optimum. Slower chemical function, repair, and disposal of local and environmental toxins puts the body below expected function. This can cause many syndromes and symptoms, such as those listed to the right. Obviously, not all chronic problems are related to chronic low body temperature; but if several of these are noted, it may be prudent to measure one's body temperature on a routine basis to see if low body temperature is a possibility.

Heat and temperature

heat:is energy in transit it is transmitted between bodies wich are at different temperatures and wich come into contact with each other.

temperature:is a physical magnitude related to the amout of heat that a body can receive and absorb.it is a type of energy wich is not stored, it only appears in the transfer of energy.

heat transmission in bodies:
-conduction:is the trasmission of heat throug an solid object;example:a piece of metal in the fire.
-convention:transfers heat through an interchange of could and hot inolecules:ex heating water in a tea pot.
-radiation:is the transfers of heat by electromagnetic radiation, generally
with infrared.ex is the way a room is warmed.
