Q: What is the freezing point of water-
  • A. 40⁰ F
  • B. 42⁰F
  • C. 34⁰F
  • D. 32⁰ F
Correct Answer: Option D - The freezing point of water is 32⁰ Fahrenheit (or 0⁰C) and the density of water at 4⁰Celsius is maximum and the volume is minimum. The water is converted in to ice at 0⁰ C (32⁰ F) and the boiling point of pure water is 100⁰C and the freezing point is 0⁰ Celsius.
D. The freezing point of water is 32⁰ Fahrenheit (or 0⁰C) and the density of water at 4⁰Celsius is maximum and the volume is minimum. The water is converted in to ice at 0⁰ C (32⁰ F) and the boiling point of pure water is 100⁰C and the freezing point is 0⁰ Celsius.

Explanations:

The freezing point of water is 32⁰ Fahrenheit (or 0⁰C) and the density of water at 4⁰Celsius is maximum and the volume is minimum. The water is converted in to ice at 0⁰ C (32⁰ F) and the boiling point of pure water is 100⁰C and the freezing point is 0⁰ Celsius.
