Lukewarm water is mainly water that is water that has a temperature of around 20℃-25℃.

There is no strict definition of warm water in general, nor is there a strict scientific definition of warm water, and the temperature of warm water is not always the same for everyone.

Life is often said to be warm water to the sense of touch to judge, not cold or hot, generally 25 ℃ -40 ℃ of water can be called warm water, and the body temperature close to the body.

If it is below this temperature, people will feel slightly cooler, so it is cold water. If it is below zero, it is ice water. Everyone feels water more or less differently, so you can feel it more yourself and find the right temperature for you.

The right way to measure the water temperature:

First of all, you need to prepare a thermometer, either a liquid thermometer or a digital thermometer, which can be used to measure the water temperature. It is recommended to use a liquid thermometer, which is more sensitive and accurate, and displays the numbers more clearly and easily recognizable.

Secondly, installing a thermometer and using it effectively is a basic requirement for measuring water temperature. The thermometer should be installed in the tank, water pipe or other water sample sampling point. If it is a direct measurement of water temperature in the tank, the thermometer should be immersed in the water, at least the depth of more than half of the length of the thermometer, to ensure that the thermometer inserted into the hole by having contact with the water, so that the thermometer is really submerged in the water.

Finally, turn on the power supply of the thermometer, stick the thermometer into the water, let it mix with the water, 0.5-1 minutes after the accurate water temperature can be obtained. Depending on the water source, you can adjust the measurement time appropriately so as to measure the water temperature more accurately. Through the above steps, the correct measurement of water temperature is completed.
