Concept in Definition ABC

Temperature is that property physical or magnitude that allows us to know the temperatures, that is, it gives us a complete idea of ​​how cold or hot the body of a person, an object or a certain region presents. So if we measure the temperature of a hot object, it will have a higher temperature. Temperature is closely related to Energy internal thermodynamic system of a body, while this energy, in turn, is related to the movement of the particles that make up that system, from which it follows that the higher the temperature of that sensitive system, the temperature of that body or object will be higher.

The only and most accurate way to measure temperature is through a thermometer, which may be calibrated according to various scales of measurement Of the same. The Unit of temperature in the international system of units is the Kelvin, while and outside of a scientific context we find the use of other scales such as the scale Celsius or centigrade and in those countries of Anglo-Saxon origin the Fahrenheit.

A concept closely linked to that of temperature is that of sensation thermal, because contrary to what many believe the heat or cold that we perceive will be determined by the thermal sensation than with the real temperature. For this reason, in times of very cold or very hot weather, it is usually more attention and placing greater emphasis on the sensation of cold and heat that prevails rather than on the actual temperature that is capable does not really tell us what our body feels.

So, the thermal sensation is the way in which the human body perceives the temperature of the objects and the environment, although obviously this measurement is much more complex and will be subject to and permeable to different sensations, it is possible to simulate in a thermometer the thermal sensation as it is perceived by a body human.
