the process of heating a liquid above its boiling point without its boiling
The process of heating a substance to much higher temperatures than are needed to maintain it in a gas phase.
The heating of a liquid to a temperature above its normal boiling point.
Creating a rise in temperature by adding heat energy to a refrigeration vapor.
