What is the equivalent temperature of water in Fahrenheit if the temperature in Celsius is 10 degrees?

To convert a temperature from Celsius to Fahrenheit, you can use the formula:

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

In this case, if the temperature in Celsius is 10 degrees, you would first multiply 10 by ( \frac{9}{5} ) (which is equivalent to 1.8). This results in 18. Then, you add 32 to this value:

[ 18 + 32 = 50 ]

Therefore, when the Celsius temperature is 10 degrees, the equivalent in Fahrenheit is 50 degrees.

This method makes it clear why the choice indicating 50 F is the correct answer, as it follows the standard conversion formula used to relate temperatures between these two scales.
