3. Boiling Point Table 1 shows the normal boiling points of several substances. Write a program that prompts the user for the observed boiling point of a substance in degrees Celsius and identifies the substance if the observed boiling point is within 5% of the expected boiling point. If the data input is more than 5% higher or lower than any of the boiling points in the table, it should output Unknown substance Enter the temperature: 105 105 C is the boiling point of Water. Enter the temperature: 5000 5000 C is the boiling point of unknown substance Substance Boiling Point (C) Methane Butane Water Nonane Mercury Copper Silver Gold 161.7 -0.5 100 150.8 357 1187 2193 2660 Table 1: Expected Boiling Points
