Part 1 of 2
Matter is in a liquid state when its temperature is between its melting point and its boiling point. Suppose that some substance has a melting point of - 39.67°C
and a boiling point of 387.32°C. What is the range of temperatures in degrees Fahrenheit for which this substance is not in a liquid state? (Hint: C = 5/9(F-32))
Express the range as an inequality and in interval notation.
