Room temperature, colloquially, denotes the range of air temperatures most people find comfortable indoors while dressed in typical clothing. Comfortable temperatures can be extended beyond this range depending on humidity , air circulation , and other factors.
West Virginia is situated in the Appalachian Mountains of the Upper South region of the 48 contiguous states. Usually considered part of the South Eastern United States, West Virginia is bounded on the northeast by Pennsylvania and Maryland, on the southeast by Virginia, on the northwest by Ohio, and on the southwest by Kentucky.
The part of the bleed air that is directed to the ECS is then expanded to bring it to cabin pressure, which cools it. A final, suitable temperature is then achieved by adding back heat from the hot compressed air via a heat exchanger and air cycle machine known as a PAC (Pressurization and Air Conditioning) system. In some larger airliners, hot ...
A 2022 Outside article on heat stroke cites the highest known body temperature that a human was able to survive: “The highest body temperature measured was only 17 degrees above normal. Willie ...
High humidity and low temperatures cause the air to feel chilly. [37] Cold air with high relative humidity "feels" colder than dry air of the same temperature because high humidity in cold weather increases the conduction of heat from the body. [38] There has been controversy over why damp cold air feels colder than dry cold air.
The temperature of the air near the surface of the Earth is measured at meteorological observatories and weather stations, usually using thermometers placed in a shelter such as a Stevenson screen—a standardized, well-ventilated, white-painted instrument shelter. The thermometers should be positioned 1.25–2 m above the ground.
The temperature of the atmosphere decreases by a lapse rate, mostly caused by convection and the adiabatic expansion of air with decreasing pressure. [44] At the peak of Mount Everest, the average summer temperature is −19 °C (−2 °F) and the average winter temperature is −36 °C (−33 °F). [45]
The only mechanism the human body has to cool itself is by sweat evaporation. [5] Sweating occurs when the ambient air temperature is above 35 °C (95 °F) [dubious – discuss] and the body fails to return to the normal internal temperature. [18] The evaporation of the sweat helps cool the blood beneath the skin.
