Question 1128498: In a chemistry class, students were learning about boiling point of various elements.Reuben has compiled a table that gives boiling points of each of various elements.
The lowest boiling point is of Element X: � 200 degrees Fahrenheit.
The highest boiling point is of Element Y: 550 degrees Fahrenheit
Find the difference between the lowest and highest boiling point.
I know how to calculate the difference.
-200 � 550 = -750.
I am not sure if the answer is written as a negative or positive. Isn�t difference in temperature always written as its absolute value?
Will the answer be � 750 F or 750 F ?
Would greatly appreciate if you could explain what the correct answer is.
