Is it true that water (steam and ice) can not get hotter than 212 degrees and colder than 32 degrees? A: It is not true that water can only get up to 212 degrees and as cold as 32 degrees. After water changes from a liquid to a gas (at 212 degrees Fahrenheit) it can actually heat up much hotter than that.
Does water get hotter as it boils?
If your pot has a very very smooth surface all around its inside, and you heat it gradually, it can become ‘super heated’, and exist at higher temperatures than 100°C. After that, when it starts bubbling, it will cool to 100°C. And the amount that it goes over isn’t a whole lot. But it is measurable.
How hot is steam coming from boiling water?
We learned that water has three states: ice is the solid state, water vapor is the gaseous state, and water is the liquid state. When water is heated it evaporates, which means it turns into water vapor and expands. At 100℃ it boils, thus rapidly evaporating. And at boiling point, the invisible gas of steam is created.
