Question

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 -43,26°C and a boiling point of 322.13°CWhat is the range of temperatures in degrees Fahrenheit for which this substance is not in a liquid state? (Hint: C = (F-32)) Express the range as an inequality. Let x represent the temperature in degrees Fahrenheit. What is the range of temperatures for which this substance is not in a liquid state?

Answer 1

x < 7.967 °F or x > 210.961°F

Explanation:

The conversion formula from Celcius to Fahrenheit is:

`F = (5)/(9) C + 32\\F_(melt) = (5)/(9) (-43.26) + 32 = 7.967\\F_(boil) = (5)/(9) (322.13) + 32 = 210.961`

It will NOT be in a liquid state outside of this range.
