At sea level-standard atmospheric pressure, the boiling point of water is 99.974°C or 212 F or 373.5438+05 K. When the water is lower than the boiling point, it can also slowly evaporate into steam. However, in the extremely low pressure environment (below 0.006 atmospheric pressure), ice will sublimate directly into water vapor. Water vapor may cause the greenhouse effect. It is a greenhouse gas.

Pay attention to this question:
Oven preheating:
Before baking any food, the oven needs to be preheated to the specified temperature to meet the baking time in the recipe. It takes about time to preheat the oven. If it is insufficient, the specified temperature may not be reached. If the preheating time of the oven is too long, it may also affect the service life of the oven.
Baking height:
To bake things in a small oven, basically you just need to put the food in, but a medium-sized oven generally contains three layers of height to choose from. As long as the temperature of fire and water is not specified in the recipe, the baking tray can be placed in the middle layer.
If the upper fire temperature is high and the lower fire temperature is low, unless the upper and lower fire temperatures of the oven can be adjusted separately, it is generally that the upper and lower fire temperatures are added and divided by two, and then the baking tray can be placed on the upper layer, but always pay attention to whether the surface is burnt.
