What is known as Latent heat of sublimation?

The latent heat of sublimation refers to the amount of heat energy required for a substance to transition directly from its solid phase to its gas phase at constant temperature and pressure. Unlike melting or boiling, sublimation occurs without the substance passing through the liquid phase. During sublimation, the substance absorbs energy to overcome the intermolecular forces that hold its solid lattice together. This energy is used to break these bonds and allow the substance to change phase into a gas. The latent heat of sublimation is a specific property of each substance and depends on its molecular structure and the type of intermolecular forces present. For example, dry ice (solid carbon dioxide) has a latent heat of sublimation of approximately 571 kJ/kg, indicating that this amount of energy is required to convert one kilogram of dry ice directly into gaseous carbon dioxide.
