Water is heated to 145 °F. What is the temperature of the hot water in degrees Celsius?

Guida verificata passo dopo passo

Step 1: Recall the formula for converting Fahrenheit to Celsius: \( T_{C} = \frac{5}{9} \times (T_{F} - 32) \), where \( T_{C} \) is the temperature in Celsius and \( T_{F} \) is the temperature in Fahrenheit.

Step 2: Substitute the given Fahrenheit temperature (145 °F) into the formula: \( T_{C} = \frac{5}{9} \times (145 - 32) \).

Step 3: Perform the subtraction inside the parentheses: \( 145 - 32 \).

Step 4: Multiply the result of the subtraction by \( \frac{5}{9} \).

Step 5: The final result will give the temperature in degrees Celsius.

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.

Temperature Conversion

Temperature conversion is the process of changing a temperature value from one unit to another, such as from Fahrenheit to Celsius. The formula for converting Fahrenheit to Celsius is C = (F - 32) × 5/9, where F is the temperature in Fahrenheit and C is the temperature in Celsius. Understanding this formula is essential for accurately converting temperatures.

Fahrenheit Scale

The Fahrenheit scale is a temperature scale where water freezes at 32 degrees and boils at 212 degrees under standard atmospheric conditions. It is primarily used in the United States and a few other countries. Familiarity with this scale is important for interpreting temperature readings and performing conversions to other scales.
