Infinite , is the correct answer for this question
They are not two different temperatures. They are two different
descriptions of the same temperature, using different-size degrees
and different scales. A lot like "60 miles per hour" and "96.6 kilometers
per hour" ... the same speed.
In the case of the temperatures, the tags " °F " and " °C " show that the
units are different. And even though it's not obvious from the descriptions,
they also start counting at different temperatures.
Nearly everything in science is considered a "theory" because there isn't enough evidence to prove it to be a fact. So,if more evidence is discovered,a theory will become a fact,or if evidence is discovered disproving a theory,the theory is no longer even valid as a theory.
