it is important first to define what is warm water. For the human point of view, it is when you touch it and feel that it is warm and this is linked to your perception, your body temperature and what part of your body you are using to test the temperature. Going to the swimming pool every week, I can tell you that my hand and the rest of my body do not have the same definition of warm water...
When the water is slightly over your body temperature, it will be considered usually as warm by people...
(you could also ask the question, how old are you when you are old).
20 degrees Celsius is 68 degrees Fahrenheit and that is warm.
Warm... 30 degrees Celsius is approximately 86 degrees Fahrenheit
A "degree" on the Celsius scale is larger than a "degree" on the Fahrenheit scale. There are 100 equal intervals (degrees) between 0 °C and 100 °C, the freezing and boiling points of water. There are 180 equal intervals between those same temperatures on the Fahrenheit scale (32 °F and 212 °F). That makes each Celsius degree 1.8 times as large (wide) an interval as the Fahrenheit degree. This is the basis for the "9/5" an "5/9" fractions in the conversion formulas (9/5 = 1.8). Some conversion formulas omit the fractions in favor of multiplying or dividing by 1.8, which is a single step. (see related questions)
28 degree Celsius = 82.4 degree Fahrenheit.
14 degree Fahrenheit = -10 degree Celsius
If it is Fahrenheit, not much. If it is centigrade, you get lizard liver soup.
Ice (frozen water) melts at 32 degrees Fahrenheit.
32ºF
32
32 degree Fahrenheit.
The temperature of warm water is typically between 90 to 110 degrees Fahrenheit.
20 degrees Celsius is 68 degrees Fahrenheit and that is warm.
On the Fahrenheit scale, water freezes, or melts, at 32 degrees. Likewise, water freezes at 0.0 Celsius.
Warm... 30 degrees Celsius is approximately 86 degrees Fahrenheit
32 is the temperature in degrees Fahrenheit at which water freezes
At 35 degrees Fahrenheit, water is in a frozen state. To boil water, you need to increase the temperature to 212 degrees Fahrenheit (100 degrees Celsius) at sea level. This increase in temperature is necessary to overcome the intermolecular forces holding water molecules together in the liquid state.
Water at 100 degrees Fahrenheit would feel very warm to the touch, nearing the temperature of a typical hot tub. It would likely feel pleasant at first but could quickly become uncomfortable or even scalding if exposed for too long.
