Problem 1 Easy Difficulty

Convert the following Celsius temperatures to Fahrenheit: (a) -62.8$^\circ$C, the lowest temperature ever recorded in North America (February 3, 1947, Snag, Yukon); (b) 56.7$^\circ$C, the highest temperature ever recorded in the United States (July 10, 1913, Death Valley, California); (c) 31.1$^\circ$C, the world’s highest average annual temperature (Lugh Ferrandi, Somalia).


(a) $T_{\mathrm{F}}=(9 / 5)(-62.8)+32=-81.0^{\circ} \mathrm{F}$
(b) $T_{\mathrm{F}}=(9 / 5)(56.7)+32=134.1^{\circ} \mathrm{F}$
(c) $T_{\mathrm{F}}=(9 / 5)(31.1)+32=88.0^{\circ} \mathrm{F}$

No, he was simply converting Fahrenheit worlds other Celsius to Fahrenheit. We know that the conversion from from Celsius to Fahrenheit would be nine over five times the temperature and Celsius plus 32 So we can say for party, the temperature and Fahrenheit would be equal to 9/5 times negative 62.8 degrees Celsius plus 32. This is giving us negative 81 degrees Fahrenheit. For Part B, the temperature and Fahrenheit would be equal to nine over five times 56.7 degrees Celsius plus 32 So this is equally 134 degrees Fahrenheit for part. See, we find that the temperature and Fahrenheit is going to be 9/5 now. Here it's going to be 31.1 degree Celsius, plus 30 to the temperature and Fahrenheit would be 88 degrees Fahrenheit. So these would be your three answers. That is the end of the solution. Thank you for watching
