Blend, or mix, refers to the process of combining two or more substances to create a uniform mixture. This can involve liquids, solids, or gases, and is commonly seen in cooking, where ingredients like flour and sugar are blended to make batter. Blending can also occur in various industries, such as cosmetics, where different ingredients are mixed to create products like lotions or creams. In science, blending is important for creating solutions or suspensions. For example, when salt is mixed with water, it dissolves to form a saline solution. The blending process can affect the properties of the final product, such as texture, flavor, or color, making it a crucial step in many applications.
