Answer:
When water is heated above its boiling point without boiling, the process is called Superheating.
Step-by-step explanation:
It is possible to heat a liquid beyond its boiling point yet the liquid will not boil. Superheating is can be carried out by heating a homogeneous substance such as very clean, uncontaminated water in a clean container, free of nucleation sites, while taking care not to disturb the liquid.
Lately, it has also been confirmed that superheating does occur in impure substances also.
