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. Will the answer be – 750 F or 750 F ? Would greatly appreciate if you could explain what the correct answer is.
