What type of heat is described as potential heat bound up in the form of a material?

Latent heat refers to the heat energy that is absorbed or released by a substance during a phase change without a change in temperature. This means that latent heat is essentially the potential heat stored in a material in forms such as solid, liquid, or gas. For example, when water transitions from ice to liquid, it absorbs heat without a temperature increase until the phase change is complete, showcasing how heat is stored as potential energy within the material.

As for other types of heat, sensible heat is the heat that causes a change in temperature and can be felt through temperature change, making it distinct from latent heat. Invisible heat generally refers to heat that cannot be sensed directly, which may overlap with latent heat but does not specifically define the potential heat aspect. Conductive heat pertains to the transfer of heat through materials via direct contact, which is also different from the concept of heat storage in a material's potential form.
