Why doesn’t the water boil in the sauna and bath? A visit to the sauna or bath is an excellent opportunity to combine the pleasure of water procedures with significant health benefits. So, for example, why does the water not boil while in a hotly heated room? After all, a thermometer in a steam room can reach the level of +100, 120 degrees, especially if measurements are taken directly under the ceiling.

Why doesn’t the water in the sauna boil at such temperature indicators? Even from the school course, everyone knows that it should boil at 100 degrees.

The process of heating water and air

Resting in the hot summer near the reservoir, it can be noted that the water is almost always cooler than air. There is a completely natural reason for this. Air is a more discharged substance, a gas of low density, it quickly heats up and quickly cools under the temperature changes that are observed when changing day and night, in any other circumstances. Water, on the other hand, is a denser substance; it warms up not so fast, and it cools not so quickly. It is able to transfer heat or cool air, forming the famous sea breezes. The oceans form the climate of the planet - in coastal areas it is not so cold in winter and not so hot in summer just due to water, which can both accumulate and give off heat. The continental climate is more severe than the seaside one.

Air heats water with difficulty, having a lower density than liquid.Being in the steam room, the water in the basin or bath will gradually heat up. After a few hours, it can even become hot, but it does not boil, since the air temperature will not be transferred to it completely.

Heating water in contact with denser substances

But when in contact with hot solids with high thermal conductivity, the water will boil very quickly. Having a high density and high thermal conductivity, the metal or brick of the furnace can easily transfer temperature to water, especially since it sometimes heats up to more than 100 degrees, transferring heat to the surrounding air only partially. He will heat the water in a matter of minutes.

Interesting fact: if the air had such a high thermal conductivity that it would be able to boil water at a temperature of 100 degrees, not a single person could visit a sauna or a bath.

Where will the water warm faster?

Wanting to boil water, it is reasonable to put it on the stove. Here it will warm up the fastest and boil in a matter of minutes. Experimenting and looking for the hottest places in the sauna, a person should keep in mind that they are directly under the ceiling. Of course, the water there does not boil, but those who like extreme temperatures and prefer to steam in the hottest bath or sauna should take the upper shelves. And vice versa, people who do not like heat or can hardly stand it, have health problems, do not want to overload the cardiovascular system, should occupy shops lower. The closer to the floor, the less heat is felt.

This is natural; the laws of physics easily explain this fact. Warm air rises upward, it is lighter than cold air, since when heated all bodies expand, atoms and molecules move away from each other at a greater distance than that of a cooled substance. When cooled, all substances are compressed. Warm water also usually appears in the upper layers - not only because here it is warmed up more by the sun.

Thus, water does not boil in a sauna or in a steam room even at high air temperatures, since air has a lower thermal conductivity and density than water. It can warm up from the air, and quite a lot, but it will take a lot of time. But the water will quickly boil on the stove, and when it is splashed onto the stove, it will instantly turn into steam. If water could completely take the temperature from the air and boil at its rate of 100 degrees, people could not go to the bathhouse. The hottest place in any steam room is above, under the ceiling, where warm air rushes, and the coolest thing is below.
