Vacuum distillation is a separation process that involves distilling a liquid under reduced pressure. By lowering the pressure, the boiling point of the liquid is decreased, which allows for the separation of components at lower temperatures. This technique is particularly useful for separating substances that are thermally sensitive, volatile, or have high boiling points that would decompose if heated to those temperatures at atmospheric pressure.

Vacuum evaporation is a physical process used to separate or purify substances by utilizing low pressure (a vacuum) to lower the boiling point of the liquid being evaporated. This technique is widely used in various industrial applications, including: 1. **Concentration**: For concentrating solutions, commonly in the food and chemical industries. For example, it is used to concentrate fruit juices or liquid flavors without altering their properties significantly due to high temperatures.

Vacuum packing is a method of preserving food and other perishable items by removing air from the packaging before sealing it. This process involves placing the items in a plastic bag or container, then using a vacuum sealer to extract the air and create a tight seal. Without air, the growth of bacteria, mold, and yeast is slowed, which helps to extend the shelf life of the food and maintain its quality.

A vacuum pump is a device that removes gas molecules from a sealed volume to create a vacuum, or a space with significantly reduced pressure compared to the ambient atmospheric pressure. It works by extracting air and other gases from a designated area, thus lowering the pressure within that area. **Types of Vacuum Pumps:** 1. **Positive Displacement Pumps**: These pumps create a vacuum by trapping a volume of gas and then expelling it from the system.
