In the video above, which piece of equipment is the major difference between evaporation and distillation?

The major difference between evaporation and distillation lies in the equipment used for distillation. Distillation involves the use of a distillation apparatus, which typically includes a distillation flask, condenser, and receiving flask. This setup allows for the separation of components based on their boiling points by heating the liquid to create vapor, which is then cooled and condensed back into a liquid form.

In contrast, evaporation does not require specialized equipment; it can simply occur in an open container at room temperature or with the application of heat without the need for condensing and collecting the vapor. Thus, the key equipment that distinguishes the two processes is the distillation apparatus used in distillation.
