what temp is freezing point
The freezing point of (pure) water is 0 degrees Celsius, which is the same as 32 degrees Fahrenheit.
If you’re seeing slightly different numbers in experiments or online discussions, that’s usually because:
- Pressure isn’t exactly “standard” (sea-level) conditions.
- The water has dissolved substances like salt or minerals, which lower its freezing point.
- Water can sometimes be “supercooled,” staying liquid a bit below 0 °C before it suddenly freezes.
In everyday weather reports, “freezing” generally means 0 °C / 32 °F or colder.
