An operating temperature is the allowable temperature range of the local ambient environment at which an electrical or mechanical device operates. The device will operate effectively within a specified temperature range which varies based on the device function and application context, and ranges from the minimum operating temperature to the maximum operating temperature (or peak operating ...
The autoignition temperature is the lowest temperature at which the substance will ignite without an additional heat or ignition source (at atmospheric pressure). This temperature is used for classification for industry and technology applications.
The ASME Boiler & Pressure Vessel Code ... Low Temperature Operation: UCS-65 through to UCS-68; 1:* Fabrication: UCS-75 through to UCS-85 Inspection and Tests: UCS-90;
The National Electrical Code (NEC), or NFPA 70, ... In certain situations, temperature rating can be higher than normal, ...
The spectral class of a star is a short code primarily summarizing the ionization state, giving an objective measure of the photosphere's temperature. Most stars are currently classified under the Morgan–Keenan (MK) system using the letters O , B , A , F , G , K , and M , a sequence from the hottest ( O type) to the coolest ( M type).
Aerial photograph of Vostok Station, the coldest directly observed location on Earth. The location of Vostok Station in Antarctica. The lowest natural temperature ever directly recorded at ground level on Earth is −89.2 °C (−128.6 °F; 184.0 K) at the then-Soviet Vostok Station in Antarctica on 21 July 1983 by ground measurements.
This is a list of countries and sovereign states by temperature. Average yearly temperature is calculated by averaging the minimum and maximum daily temperatures in the country, averaged for the years 1991 – 2020, from World Bank Group , derived from raw gridded climatologies from the Climatic Research Unit .
The temperature reading depends on which part of the body is being measured. The typical daytime temperatures among healthy adults are as follows: Temperature in the anus (rectum/rectal), vagina, or in the ear (tympanic) is about 37.5 °C (99.5 °F) [20] [medical citation needed] Temperature in the mouth (oral) is about 36.8 °C (98.2 °F) [12]
