Can boiling water exceed 212 degrees?

Liquid water can be hotter than 100 °C (212 °F) and colder than 0 °C (32 °F). Heating water above its boiling point without boiling is called superheating. If water is superheated, it can exceed its boiling point without boiling. … Once water freezes into ice, the ice can be cooled all the way down to absolute zero.

What is the difference between a boil and a rolling boil?

However, in general, a simmer is when you barely have any bubbles at all. It’s right at the edge between definitely liquid and maaaybe gas. A full or rolling boil is when you are making bubbles so quickly that no amount of sitting on the stove is going to make more bubbles come quickly.

What are the stages of a boil?
