breakdown

Breakdown is when something stops working or stops being useful.

In science, breakdown can mean different things depending on the context. For example, in chemistry, breakdown can refer to the process of a chemical compound breaking down into smaller molecules. In biology, breakdown can refer to the process of a living organism dying and its body breaking down into smaller pieces.

Here are some examples of breakdown in science:

• Chemical breakdown: When a chemical compound breaks down into smaller molecules, it is called chemical breakdown. For example, when a piece of wood burns, it breaks down into carbon dioxide and water.
• Chemical breakdown
• Biological breakdown: When a living organism dies and its body breaks down into smaller pieces, it is called biological breakdown. For example, when a dead animal is buried in the ground, it breaks down into soil over time.
• Biological breakdown
• Mechanical breakdown: When a machine or piece of equipment stops working because it has been damaged, it is called mechanical breakdown. For example, if a car's engine breaks down, it will stop working.
