What is the current temperature in Fahrenheit of water that started at 15°C and is now at 80°C?

• A. 176°F
• B. 160°F
• C. 120°F
• D. 180°F

Answer: (A)

To determine the current temperature of water in Fahrenheit after conversion from Celsius, we can use the formula for converting Celsius to Fahrenheit: \[ F = \left( C \times \frac{9}{5} \right) + 32 \] Here, \( C \) is the temperature in Celsius. In this case, the water is at 80°C. Using the formula: 1. Multiply 80 by \( \frac{9}{5} \): \[ 80 \times \frac{9}{5} = 144 \] 2. Add 32 to the result: \[ 144 + 32 = 176°F \] Thus, the temperature of the water at 80°C is 176°F. This shows that the process of converting Celsius temperatures into Fahrenheit properly modernizes the unit of measure to make sense in contexts where Fahrenheit is commonly used, notably in certain regions such as the United States. Understanding this conversion is crucial, especially in fields related to instrumentation and process control, where temperature readings can be critical for safety and operational efficiency.

To determine the current temperature of water in Fahrenheit after conversion from Celsius, we can use the formula for converting Celsius to Fahrenheit:

[ F = \left( C \times \frac{9}{5} \right) + 32 ]

Here, ( C ) is the temperature in Celsius. In this case, the water is at 80°C.

Using the formula:

1. Multiply 80 by ( \frac{9}{5} ):

[ 80 \times \frac{9}{5} = 144 ]

2. Add 32 to the result:

[ 144 + 32 = 176°F ]

Thus, the temperature of the water at 80°C is 176°F. This shows that the process of converting Celsius temperatures into Fahrenheit properly modernizes the unit of measure to make sense in contexts where Fahrenheit is commonly used, notably in certain regions such as the United States.

Understanding this conversion is crucial, especially in fields related to instrumentation and process control, where temperature readings can be critical for safety and operational efficiency.
