c °C to f °F: f = c × 1.8 + 32; f °F to k K: k = f + 459.67 / 1.8 k K to f °F: f = k × 1.8 − 459.67; There is also an exact conversion between Celsius and Fahrenheit scales making use of the correspondence −40 °F ≘ −40 °C. Again, f is the numeric value in degrees Fahrenheit, and c the numeric value in degrees Celsius:
Neutral C 60 has been observed in planetary nebulae [7] and several types of star. [8] The ionised form, C 60 +, has been identified in the interstellar medium, [9] where it is the cause of several absorption features known as diffuse interstellar bands in the near-infrared. [10]
The family is named after buckminsterfullerene (C 60), the most famous member, which in turn is named after Buckminster Fuller. The closed fullerenes, especially C 60, are also informally called buckyballs for their resemblance to the standard ball of association football ("soccer"). Nested closed fullerenes have been named bucky onions.
* Normal human body temperature is 36.8 °C ±0.7 °C, or 98.2 °F ±1.3 °F. The commonly given value 98.6 °F is simply the exact conversion of the nineteenth-century German standard of 37 °C. Since it does not list an acceptable range, it could therefore be said to have excess (invalid) precision.
However, there are some schools that consider a C the lowest passing grade, so the general standard is that anything below a 60% or 70% is failing, depending on the grading scale. In post-secondary schools, such as college and universities, a D is considered to be an unsatisfactory passing grade.
Celsius (°C) Fahrenheit (°F) Rankine (°R or °Ra), which uses the Fahrenheit scale, adjusted so that 0 degrees Rankine is equal to absolute zero. Unlike the degree Fahrenheit and degree Celsius, the kelvin is no longer referred to or written as a degree (but was before 1967 [1] [2] [3]). The kelvin is the primary unit of temperature ...
Within two minutes, a heat burst reportedly drove the air temperature from 38 °C (100 °F) to 70 °C (158 °F). [22] [23] 1960: 60 °C (140 °F) Air Kopperl, Texas (United States) A heat burst is claimed to have sent the air temperature to near 140 °F (60 °C), supposedly causing cotton crops to become desiccated and drying out vegetation. [24]
The calculated data allows using C 60 fullerene as a Faraday cage, [13] which isolates the encapsulated atom from the external electric field. The mentioned relations should be typical for the more complicated endohedral structures (e.g., C 60 @C 240 [14] and giant fullerene-containing "onions" [15]).
