Figure 4 2.5 2.0 1.5 TTTTTTTTTT Es [W m-2 nm-'] 1.0 0.5 O.OL 0 500 1000 1500 2000 2500 3000 wavelength [nm] F. The hottest day on Earth is on record as 213F (ironically in the Death Valley Dessert of California). Note: there is some debate on the validity of this measurement from 1913. Use the formula below to covert this into Kelvin and answer question 15. T(Kelvin) = (T(Fahrenheit) + 459.67) x 0.556 15. Hottest day on earth in Kelvin = G. To find out how many times hotter the surface of the Sun is compared to the hottest day on the surface of earth, divide the temperature of the surface of the sun (number 14) by the hottest day on earth in Kelvin (number 15). Mark this answer for number 16. 16. Suface Temperature of Sun Hottest day on earth Times Hotter than Earth
