For an exact conversion between degrees Fahrenheit and Celsius, and kelvins of a specific temperature point, the following formulas can be applied. Here, f is the value in degrees Fahrenheit, c the value in degrees Celsius, and k the value in kelvins: f °F to c °C: c = f − 32 / 1.8 c °C to f °F: f = c × 1.8 + 32
This is a list of cities by average temperature (monthly and yearly). The temperatures listed are averages of the daily highs and lows. Thus, the actual daytime temperature in a given month may be considerably higher than the temperature listed here, depending on how large the difference between daily highs and lows is.
In an average year, the temperature will usually be between 8 °F (−13 °C) and 97 °F (36 °C) with temperatures greatly exceeding these values being uncommon. Temperatures above 100 °F (38 °C) and below 0 °F (−18 °C) are very rare, with the last occurrences being July 18, 2012 and February 14, 2016, respectively. [17]
The wet-bulb temperature is the lowest temperature that can be reached under current ambient conditions by the evaporation of water only. Even heat-adapted people cannot carry out normal outdoor activities past a wet-bulb temperature of 32 °C (90 °F), equivalent to a heat index of 55 °C (131 °F). A reading of 35 °C (95 °F) – equivalent ...
Canada's annual average temperature over land has warmed by 1.7 °C (3.1 °F), with changes ranging from 1.1 to 2.3 °C (2.0 to 4.1 °F) in various regions, since 1948. [4] The rate of warming has been higher across the North and in the Prairies. [ 4 ]
The city's all-time recorded high temperature is 113 °F (45 °C) during the Heat Wave of 1980. In July and August, the average high temperature is near 96 °F (36 °C), while the average nighttime low temperature is around 77 °F (25 °C). Days with temperatures exceeding 100 °F (38 °C) happen at least several times during the summer every year.
In February 2015, Rochester experienced its coldest month ever, with an average temperature of 12.2 °F (−11 °C). [7] Later, 2015 had a near-record warm November and a record-breaking December. December 2015 was about 12 degrees F warmer than average, and several degrees over the previous record.
c P,m = c V,m + R = 1 / 2 fR + R = 1 / 2 (f + 2)R. Thus, each additional degree of freedom will contribute 1 / 2 R to the molar heat capacity of the gas (both c V,m and c P,m). In particular, each molecule of a monatomic gas has only f = 3 degrees of freedom, namely the components of its velocity vector; therefore c V,m ...
