definition of temperature

Temperature is that physical property 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 is.. So, if we measure the temperature of a hot object, it will have a higher temperature. The temperature is closely related to the internal energy of the 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, the or which may be calibrated according to various scales of measurement thereof. 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 Celsius or centigrade scale and in those countries of Anglo-Saxon origin the Fahrenheit.

A concept closely linked to temperature is that of thermal sensation, because contrary to what many believe, the heat or cold that we perceive will be determined by the thermal sensation than with the actual temperature.. That is why in times of very cold or very hot weather, more attention is usually paid and more emphasis is placed on the sensation of cold and heat that prevails more than on the real temperature that can not really tell us what our body feels.

Then, the thermal sensation is the way in which the human body perceives the temperature of 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 the thermal sensation in a thermometer as perceived by a human body.
