Many gyms and health clubs have steam saunas with hot rocks

How can hot rocks be used to make steam in a sauna?

Why do you think only a small ladle-full of water is poured on the rocks at one time?

Answer:

The hot rocks in a steam sauna are used to heat up a small amount of water poured on them, creating steam. The heat from the rocks causes the water to evaporate and turn into steam, which then fills the room.

Hot rocks are used in steam saunas to create steam through the process of evaporation. When water is poured on the hot rocks, the heat from the rocks causes the water to quickly evaporate and turn into steam.

The reason why only a small ladle-full of water is poured on the rocks at one time is to maximize the amount of steam produced. By using a small amount of water, the heat from the rocks can quickly evaporate the water into steam. This allows for a continuous supply of steam to fill the sauna without wasting excess water.

The heat vaporization of water is very high, so with small amounts of water poured onto the hot rocks, the water can quickly vaporize and turn into steam. This ensures that the steam sauna remains at the desired temperature and humidity levels for a relaxing and rejuvenating experience.
