Lukewarm temperature for yeast is typically around 100-110F (37-43C).
The temperature of water that is considered lukewarm is typically around 98-105 degrees Fahrenheit.
Just a little bit above cold, somewhere around body heat. Body heat is 98.6°F or 37.0°C. So lukewarm would fall roughly somewhere between 79 - 97 °F or 26 - 36°C.
Only if mixed with water of a hot temperature. If it's lukewarm or below it should be ok.
Yeast needs lukewarm water, sugar, and oxygen to reproduce
Lukewarm temperature typically ranges from about 90°F to 110°F (32°C to 43°C). It is often described as being comfortably warm, neither hot nor cold. This temperature is commonly used in cooking and baking, especially for activating yeast or warming liquids.
Tepid can also be considered "lukewarm", which is room temperature (or slightly above): 23 C or 73 F
Hot water is warmer than tepid water. Tepid water typically refers to water that is lukewarm or slightly warm, while hot water is heated to a higher temperature.
Water is lukewarm when it is slightly above your temperature, about 100-105 degrees F.
The degree for lukewarm temperature can vary, but it is typically around 90-98 degrees Fahrenheit (32-37 degrees Celsius). Lukewarm generally refers to a moderate or slightly warm temperature that is neither hot nor cold.
Water at 95°F is considered warm. This temperature falls within the range of lukewarm to warm water.
Yeast does different things based on temperature.
Perhaps about 75 or 80 degrees Lukewarm is generally around body heat. ≈ 36 oC or 98 oF
