Final answer:
To convert 100º Celsius, which is the boiling point of water, to the Fahrenheit scale, the equivalent temperature is 212º F.
Step-by-step explanation:
The question 100º Celsius = ____ Fahrenheit (the boiling point of water) asks to convert a temperature from the Celsius scale to the Fahrenheit scale. In the Fahrenheit scale, the freezing point of water is 32º F, and the boiling point is 212º F. To convert from Celsius to Fahrenheit, you can use the relationship that one degree Celsius is equivalent to 1.8 degrees Fahrenheit, or specifically for the boiling point of water, which is known: 100º C is equal to 212º F. Therefore, the correct answer is c) 212º F, which is the boiling point of water on the Fahrenheit scale.
