32 degrees F
0 degrees C
The temperature reading that is the same on both Celsius and Fahrenheit scales is -40 degrees.
That's both the "Celsius" and the "Kelvin" scales.
The temperature -40 degrees is the same value in both Celsius and Fahrenheit scales.
The starting temperature will certainly affect the time it takes for water to freeze. By definition, the temperature will be the same for both the water that started warm as it is for the water that started cool when they both freeze. The time difference comes from going from warm (~85 degrees) to freezing (32 degrees) and from cool (~50 degrees) to freezing (32 degrees).
At 0 degrees Celsius and 32 degrees Fahrenheit.
at -40 on both scales.
Yes, in the Kelvin scale, freezing temperature of water is 273.15 K, while in the Celsius scale it is 0 degrees Celsius.
Both are used to measure temperature. A difference of 1 degree is the same in both scales. The only difference is the starting point. The lowest possible temperature (absolute zero) is 0 Kelvin; this is equivalent to 273.15 degrees Celsius. Thus, on the Kelvin scale there are no negative temperatures, by definition.
At -40 degrees on both scales.
The temperature when both the Celsius and Fahrenheit scales are the same is - 40 degrees.
-40 is the same on both the Celsius and Fahrenheit scales.
-40 (minus forty) degrees is the same on both temperature scales.
