(a) A child has a fever of 101 °F. What is the temperature in °C?
Guida verificata passo dopo passo1
Identify the formula to convert Fahrenheit (F) to Celsius (C). The formula is: \( C = \frac{5}{9} \times (F - 32) \).
Substitute the given Fahrenheit temperature into the formula. In this case, F = 101.
Subtract 32 from the Fahrenheit value.
Multiply the result by \( \frac{5}{9} \).
The result from the previous step will give you the temperature in Celsius (C).

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.
Temperature Scales
Temperature can be measured in different scales, primarily Celsius (C) and Fahrenheit (F). The Fahrenheit scale is commonly used in the United States, while Celsius is used in most other countries. Understanding the relationship between these scales is essential for converting temperatures accurately.

The pH Scale
Conversion Formula
To convert Fahrenheit to Celsius, the formula used is C = (F - 32) × 5/9. This formula allows for the accurate transformation of a temperature reading from one scale to another, which is crucial for interpreting temperature data in different contexts.
