The average temperature of the Sun's cores is about 2.7 * 10^7 degrees Fahrenheit. The average temperature of the Sun's photosphere is about 1/2,500 the temperature of the core. First, estimate the temperature of the Sun's photosphere. Then, find the actual temperature.

Solution:

estimate = 2.7 * 10^7 /2,500 = 1* 10^4 degrees Fahrenheit

actual =2.7 * 10^7 /2,500 = 1.08 * 10^4 degrees Fahrenheit
