SUBLIMATION: It is a process in which a solid instead of changing into liquid state changes directly into gaseous state upon heating. MELTING: It is a process in which a solid at its melting point changes into liquid state upon heating.
Melting is the process of a solid going through a physical change to the liquid state.
Sublimation is the process of a solid going immediately to the gaseous state, skipping the liquid state entirely. You can seesublimation in action by seeing a block of dry ice (frozen carbon dioxide gas) "melt" from a solid into white smoke.
Neither. Melting is the process of a solid becoming a liquid. Freezing is the process of a liquid becoming a solid. Sublimation is the process of a solid becoming a gas.
Melting is when a solid changes phase to a liquid.
Sublimation is when a solid changes phase directly to a vapour without going through the liquid phase.
The two changes of state involved in freeze drying are melting and freezing.
You should know the names of the process for these phase transitions. sublimation deposition SOLID ============> GAS ==============> SOLID melting freezing SOLID ============> LIQUID =============> SOLID (solidfication) condensation vaporization GAS =============> LIQUID =============> GAS
no it is not melting is the reverse of freezing
Melting is endothermic. Freezing is exothermic.
The change from a solid to a liquid is called melting. The opposite process, a liquid to a solid, is called freezing. When a solid turns directly to a gas, this is called sublimation.

Examples : sublimation, deposition, boiling, melting, freezing.
Particles absorb energy when boiling (vapourising), melting and subliming. Particles release energy when freezing and condensing.

melting, vaporization, sublimation, condensation, freezing, and deposition are six types of changes in matter.
Sublimation, boiling, condensation, melting and freezing. One might include evaporation, though that does not happen at a particular temperature.
