**Desiccation** is the procedure of removing water from a solid or liquid substance until it becomes extremely dry. **Evaporation** is the process in which a liquid undergoes a phase transition to become a gas.

Desiccation and evaporation are both used to eliminate moisture from a substance. Desiccation is essential in preserving organic materials, drying food, producing pharmaceuticals, and stabilizing chemicals. Evaporation plays a crucial role in water purification, distillation, and various industrial processes.

Desiccation can be carried out using various methods such as air drying, freeze drying, oven drying, and vacuum drying. Evaporation techniques include distillation, fractional distillation, and rotary evaporation.

Desiccators, vacuum ovens, and freeze dryers are employed for desiccation. Evaporators, stills, and rotary evaporators are utilized for evaporation processes.
