A change in temperature is an example of what type of heat?

A change in temperature refers to a situation where there is a measurable increase or decrease in heat energy within a substance, which directly affects its temperature. This is categorized as sensible heat. Sensible heat is the energy required to change the temperature of a substance without changing its phase. For example, heating water from room temperature to boiling involves a change in sensible heat where the temperature rises but the state remains liquid until it reaches boiling point.

Latent heat, on the other hand, involves energy being absorbed or released during a phase change, such as from solid to liquid (melting) or liquid to gas (vaporization), without a change in temperature during that process. External and internal heat are not standard terms used in thermodynamics to describe heat changes related to temperature and phase. Thus, sensible heat is the correct classification for a change in temperature alone.
