Scientific definitions for superheat
[ sōō′pər-hēt′ ]
To heat a substance above a phase-transition temperature without the transition occurring. For example, water can be heated above its boiling point without boiling; the introduction of an impurity or physical disturbance can then trigger boiling. Superheating is an example of hysteresis. Compare supercool.
