Final answer:
Baffles are used to divide liquid tanks into smaller tanks and control the movement and flow of liquids.
Step-by-step explanation:
When it comes to liquid tanks, they are divided into smaller tanks by using baffles. Baffles are barriers or partitions that are placed inside the tank to control the movement and flow of liquid. They help to prevent swaying, sloshing, and excessive movement of the liquid, ensuring stability and safety. Baffles are commonly used in various industries, including shipping and transportation, where containers need to hold liquids securely.
