TemperatureTemperaturesensation of warmth or coldness felt from contact with it.hotness and coldness of an objectdegree of sensible heat or cold, expressed in terms of a specific scale.

ThermometerThermometer An instrument for  measuring temperature, 

especially one having a 

graduated glass tube witha bulb containing a liquid, typically mercury or colored alcohol, that expands and rises in the tube as the temperature increases.

Celsius ScaleCelsius Scale the temperature difference between the reference temperatures of the freezing and boiling points of water is divided into 100 degrees. The freezing point is taken as 0 degrees Celsius and the boiling point as 100 degrees Celsius. widely known as the centigrade scale because it is divided into 100 degrees. It is named for the Swedish astronomer Anders  Celsius, who established the scale in 1742.

Fahrenheit ScaleFahrenheit Scale temperature  scale in

which the temperature difference between two reference temperatures, the melting and boiling points of water, is divided into 180 equal intervals called degrees.

The freezing point is taken as 32°F and the boiling point as 212°F.

The scale was established by the German-Dutch physicist Gabriel Daniel Fahrenheit in 1724.

Kelvin ScaleKelvin Scale  a temperature scale having an absolute zero below which temperatures do not exist.  Absolute zero, or 0°K, is the temperature at which molecular energy is a minimum, and it corresponds to a temperature of - 273.15° on the Celsius temperature scale. The Kelvin degree is the same size as the Celsius degree; hence the two reference temperatures for Celsius, the freezing point of water (0°C), and the boiling point of water (100°C), correspond to 273.15°K and 373.15°K, respectively. When writing temperatures in the Kelvin scale, it is the convention to omit the degree symbol and merely use the letter K. The temperature scale is named after the British mathematician and physicist William Thomson Kelvin, who proposed it in 1848

Rankine ScaleRankine Scale temperature scale having an

absolute zero, below which temperatures do not exist, and using a degree of the same size as that used by the Fahrenheit temperature scale.

Absolute zero , or 0°R, is the temperature at which molecular energy is a minimum, and it corresponds to a temperature of - 459.67°F.

Because the Rankine degree is the same size as the Fahrenheit degree, the freezing point of water (32°F) and the boiling point of water (212°F) correspond to 491.67°R and 671.67°R, respectively.

The temperature scale is named after the Scottish engineer and physicist William John Macquorn Rankine, who proposed it in 1859

Human body temperature is 37.0 degrees Celsius or 98.6 degrees Fahrenheit.  Cultura RM Exclusive/GIPhotoStock, Getty Images

Human thermoregulationHuman thermoregulationThermoregulation is a process that allows your body to maintain its core internal temperature. All thermoregulation mechanisms are designed to return your body to homeostasis. This is a state of equilibrium.

Bodily Maps Of EmotionBodily Maps Of Emotion Yellow or red colors indicate the areas

that felt the most stimulated, whereas blue colors highlight areas that felt deactivated. Yellow and dark blue represent the most extreme of the spectrum.

As a result researchers have data which shows both positive and negative bodily responses to different emotions.

Feelings of love and emotion were found to be at different ends of the spectrum - with the former creating a warming sensation throughout the body and the latter leaving participants feeling cold.
