Question

What is a physical and chemical change that occurs in composting?

Answer 1

Physical change: Decomposition of organic matter into smaller particles and eventually into compost. This involves the breakdown of organic materials into simpler forms through the action of microorganisms.

Chemical change: Organic compounds undergo chemical reactions such as oxidation, reduction, hydrolysis, and fermentation during composting. This results in the release of nutrients such as nitrogen, phosphorus, and potassium which are essential for plant growth.
