Question

Convert the following temperatures from the Fahrenheit scale to the Celsius and Kelvin scales. (a) The seawater temperature near Hawali is about 76 degree F. in Celsius degree C in Kelvin K (b) McDonald's was sued for serving dangerously hot coffee. Their coffee was served between 180 degree F and 190 degree F. (Give your answers in this part to at least three significant figures.) 180 degree F: in Celsius degree C in Kelvin K 190 degree F: in Celsius degree C in Kelvin K (c) The coldest day recorded on Earth was -129 degree F in Vostok, Antarctica. in Celsius degree C in Kelvin K

Explanation / Answer

Fahrenheit to Celsius : °C = 5/9 (°F - 32)

Fahrenheit to Kelvin : K = 5/9 (°F - 32) + 273

a) in celsius = 5/9 * (76 - 32) = 24.44 °C

in Kelvin = 5/9 * (76 - 32) + 273 = 297.44 K

b) 180 °F :

in celsius = 5/9 * (180 - 32) = 82.222 °C

in Kelvin = 5/9 * (180 - 32) + 273 = 355.222 K

190 °F :

in celsius = 5/9 * (190 - 32) = 87.777 °C

in Kelvin = 5/9 * (190 - 32) + 273 = 360.777 K

c) in celsius = 5/9 * (- 129 - 32) = - 89.44 °C

in Kelvin = 5/9 * (- 129 - 32) + 273 = 183.55 K
