At what temperature (in Fahrenheit) does pure water freeze under standard atmospheric pressure?

• A. 212°F
• B. 0°F
• C. 100°F
• D. 32°F

Answer: (D)

Verified step by step guidance

1. Recall that the freezing point of pure water under standard atmospheric pressure is a well-known physical property.
2. Understand that the freezing point of water is the temperature at which liquid water turns into solid ice.
3. Know the freezing point of water in Celsius is 0°C, and in Fahrenheit, it corresponds to a specific value.
4. Use the conversion formula between Celsius and Fahrenheit temperatures: \(F = \frac{9}{5}C + 32\).
5. Substitute \(C = 0\) into the formula to find the freezing point in Fahrenheit: \(F = \frac{9}{5} \times 0 + 32 = 32\)°F.
