Complete the paragraph to describe the characteristics of the sun and rigel, a blue-white supergiant.
rigel and the sun have similar characteristics, but they also differ in some ways. rigel and the sun are spheres of gas that use nuclear fusion to produce energy. rigel is ? the sun. rigel has ? the sun. rigel has a surface temperature of about?

Rigel is 74 times larger than the Sun.

Rigel has radiation 66,000 times more powerful than the Sun’s radiation output due to its output of other radiations besides visible light, the Sun.

Rigel has a surface temperature of about over 20,000 degrees, twice that of the sun and 3 1/2 times hotter than Betelgeuse.

Rigel: Astronomers classify it as a blue supergiant at a distance of 860 light years. Rigel is a massive blue supergiant calculated to be anywhere from 61,500 to 363,000 times as luminous (brighter) as the sun.  Rigel's radius is over 70 times that of the sun.  

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
