Latent Heat Equation — the NEET Physics formula with its derivation, variables, validity constraints and worked solver.
Latent Heat Equation Applies strictly during a phase change (e.g., solid to liquid, liquid to gas) where the temperature of the substance remains constant. Defined experimentally as the energy required to break intermolecular bonds without increasing kinetic energy (temperature). Linear relationship established: Energy is proportional to the amount of substance (mass). Temperature must remain constant during the process. No chemical reactions occurring. Applying Q = mcΔT during a phase change. Assuming temperature increases while ice is melting. Using the Latent Heat of Fusion for boiling processes.
