The term "hot water" is relative and can vary depending on its intended use or context. However, in general, hot water is typically considered to be between 40 to 60 degrees Celsius (104 to 140 degrees Fahrenheit).
The specific temperature can vary depending on factors such as cultural norms, safety considerations, and the purpose for which the hot water is being used. For example, in many households, the hot water supplied to taps and showers is usually set to around 50 degrees Celsius (122 degrees Fahrenheit) to balance comfort and safety, as temperatures above that can cause scalding.
It's important to note that water temperatures above 50 degrees Celsius can cause burns, and it's recommended to handle hot water with caution to avoid accidents or injuries.
