Junction temperature, short for transistor junction temperature, [1] is the highest operating temperature of the actual semiconductor in an electronic device. In operation, it is higher than case temperature and the temperature of the part's exterior.
Mean kinetic temperature (MKT) is a simplified way of expressing the overall effect of temperature fluctuations during storage or transit of perishable goods. The MKT is used to predict the overall effect of temperature fluctuations on perishable goods. It has more recently been applied to the pharmaceutical industry.
A wet-bulb temperature at 500 hPa in a tropical atmosphere of −13.2 °C (8.2 °F) is required to initiate convection if the water temperature is 26.5 °C (79.7 °F), and this temperature requirement increases or decreases proportionally by 1 °C in the sea surface temperature for each 1 °C change at 500 hpa.
Materials that must be moderately heated or exposed to relatively high ambient temperatures before they ignite: diesel fuel: 3: Liquids and solids that can ignite under almost all temperature conditions: gasoline, acetone: 4: Materials that rapidly vaporize at atmospheric pressure and normal temperatures, or readily disperse in air and burn readily

USP 800 (Hazardous Drugs—Handling in Healthcare Settings) is a guideline created by the United States Pharmacopeia Convention (USP), as one of their General Chapters through which the USP "sets quality standards for medicines, dietary supplements and food ingredients".
Some of the imprecision in the definition of the names used for mineral oil (such as 'white oil') reflects usage by consumers and merchants who did not know, and usually had no need of knowing, the oil's precise chemical makeup. Merriam-Webster states the first use of the term "mineral oil" as being 1771. [4]
Persistent cold temperatures can either prevent new snow from stabilizing or destabilize the existing snowpack. Cold air temperatures on the snow surface produce a temperature gradient in the snow, because the ground temperature at the base of the snowpack is usually around 0 °C, and the ambient air temperature can be much colder.
