breakdown

Definition

Breakdown is a process in which something is broken down into smaller parts.

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. This can happen through a variety of processes, such as oxidation, hydrolysis, and reduction. 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. This is a process that is carried out by microorganisms, such as bacteria and fungi. 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. This can happen due to a variety of factors, such as wear and tear, corrosion, or impact damage. For example, if a car's engine breaks down, it will stop working.

Mechanical breakdown

  • Breakdown is an important process in nature. It helps to recycle materials and nutrients, and it helps to prevent the buildup of waste. Breakdown is also important for human health. It helps to remove toxins from the body, and it helps to fight infection.

How can the word be used?

The number of unemployed people has shown a significant breakdown since the pandemic began.

Question

What are the main ways something can breakdown?

AQA Science Exam Question and Answer

Question:

What are the different types of chemical breakdown?

Answer:

There are many different types of chemical breakdown. Some of the most common types include:

Oxidation: Oxidation is a chemical reaction in which a substance combines with oxygen. This can happen in a variety of ways, but it often results in the formation of new compounds. For example, when a piece of wood burns, it undergoes oxidation and breaks down into carbon dioxide and water.

Oxidation.

Hydrolysis: Hydrolysis is a chemical reaction in which a substance is broken down by water. This can happen in a variety of ways, but it often results in the formation of smaller molecules. For example, when table salt is dissolved in water, it undergoes hydrolysis and breaks down into sodium and chloride ions.

Hydrolysis.

Reduction: Reduction is a chemical reaction in which a substance loses electrons. This can happen in a variety of ways, but it often results in the formation of new compounds. For example, when iron rusts, it undergoes reduction and forms iron oxide.

Reduction.

The type of chemical breakdown that occurs depends on the specific substance and the conditions under which it is broken down.
