🔬 Understanding Specific Latent Heat
Specific latent heat (L) is the energy needed to change the state of 1 kg of a substance WITHOUT changing its temperature. The word "specific" means "per kilogram."
Why does it take so much energy? Because energy must break the bonds between particles — not make them move faster. During the state change, ALL the energy goes into bond-breaking (potential energy), which is why temperature stays constant.
The bigger the latent heat value, the stronger the bonds between particles and the more energy needed to pull them apart.
