Anatomy of the human skin. Skin temperature is the temperature of the outermost surface of the body. Normal human skin temperature on the trunk of the body varies between 33.5 and 36.9 °C (92.3 and 98.4 °F), though the skin's temperature is lower over protruding parts, like the nose, and higher over muscles and active organs.

It was originally defined as the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit. It is also part of the United States customary units . [ 1 ] The SI unit for energy is the joule (J) ; one Btu equals about 1,055 J (varying within the range of 1,054–1,060 J depending on the specific definition of ...
Timeline of postmortem changes, with algor mortis represented by red temperature line. Algor mortis (from Latin algor 'coldness' and mortis 'of death'), the third stage of death, is the change in body temperature post mortem, until the ambient temperature is matched.
British settlers in Hyde Park woke up to snow "nearly 1 in (2.5 cm) deep", with the meteorological table in The Sydney Herald recording that on the morning of the snow the temperature dropped to 3 °C (37 °F). [15] 1857. New England Cold wave of 1857. January 1857 was the coldest month ever recorded in New England.
Since an increment of temperature of one degree Celsius is the same as an increment of one kelvin, that is the same as joule per degree Celsius per kilogram: J/(kg⋅°C). Sometimes the gram is used instead of kilogram for the unit of mass: 1 J⋅g −1 ⋅K −1 = 1000 J⋅kg −1 ⋅K −1 .
Lab-on-a-chip devices are a subset of microelectromechanical systems (MEMS) devices and sometimes called "micro total analysis systems" (μTAS). LOCs may use microfluidics, the physics, manipulation and study of minute amounts of fluids. However, strictly regarded "lab-on-a-chip" indicates generally the scaling of single or multiple lab ...
Earth cutaway from core to exosphere Geothermal drill machine in Wisconsin, USA. Temperature within Earth increases with depth. Highly viscous or partially molten rock at temperatures between 650 and 1,200 °C (1,200 and 2,200 °F) are found at the margins of tectonic plates, increasing the geothermal gradient in the vicinity, but only the outer core is postulated to exist in a molten or fluid ...
