Which phenomenon causes latent heat transfer during ice melting at 0°C under constant pressure?

💡 Explanation

When ice melts, heat energy is absorbed, breaking intermolecular hydrogen bonds between water molecules, allowing transition from solid to liquid while temperature nearly stays constant. Therefore, breaking hydrogen bonds accounts for latent heat, rather than vibrational/kinetic energy increases whose effect primarily drives changes of temperatures without the phase changing.
