→ Latent heat is the heat energy required to change the state of matter from a solid to a liquid, or a liquid to a gas, without changing the temperature of the substance.
→ During this process, energy is supplied to break the bonds between particles. This leads to a greater degree of freedom without increasing the kinetic energy of the particles.
→ The two stages of latent heat are the latent heat of fusion (solid to liquid) and the latent heat of evaporation (liquid to gas).
