What do we call the sensible heat added to a substance after it has turned to vapor?

The term used to describe the sensible heat added to a substance after it has turned to vapor is superheat. Superheating occurs when a vapor is heated beyond its boiling point without an increase in pressure, causing the temperature of the vapor to rise. This process is significant in various applications, particularly in steam systems and refrigeration, where effective heat transfer and thermal efficiency are crucial. In these systems, superheated vapor is essential, as it allows systems to operate more efficiently and reduces the risk of damage to components by ensuring that no liquid water is present in the system.

Latent heat, while related, refers specifically to the heat absorbed or released during the phase change of a substance, such as during the transition from liquid to vapor, but it does not pertain to the sensible heat added after vaporization. Heating heat and vapor heat are not standard terms used in thermodynamics or building maintenance, which further clarifies that superheat is the correct notation for this scenario.
