What you learn in Theory:
Latent heat is the heat released or absorbed by a body or a thermodynamic system during a constant-temperature process.
What you learn in Practice:
The terms sensible heat and latent heat are not special forms of energy; instead they characterize the same form of energy, heat, in terms of their effect on a material or a thermodynamic system.
