Vessels are containers designed to hold liquids or other substances. They come in various shapes and sizes, including cups, bottles, and tanks. Common materials used to make vessels include glass, plastic, metal, and ceramic. Each type of vessel serves specific purposes, such as storing, transporting, or serving liquids. In a broader context, the term "vessel" can also refer to large ships or boats used for maritime transport. These vessels are essential for trade and travel across oceans and rivers. Examples include cargo ships, fishing vessels, and cruise ships, all of which play significant roles in global commerce and tourism.
