Is composting cut vegetation a physical or chemical change?

Answer 1

It has both chemical and physical components

Chewing, of course, is a physical process. Additionally enzymes in the saliva and stomach break down food chemically.

Answer 2

It's a chemical change

Answer 3

It is physical property because when you recycle, it will become recycled plastic which is the same thing but it can also be chemical property because it can mix chemically with other materials. Chemica propert come in contact with natural energy, not physical power. Example:When you expose paper to fire, fire is a natural energy that burns the paper, changing the substance. (Physical propert can always be undone.)

Answer 4

It is a physcial change.

You must understand that water can be in any one of three PHYSICAL states, liquid, solid or vapor ( a gas ).

Changing physical states is not a chemical change, but a direct result of heat or cold application.

Answer 5

Modern composting is a facilitated by both mechanical (physical) and chemical change. Any instance that involves bacterial decomposition will be classifed as chemical due to the breakdown of chemical bonds present within the organic compost material. The mechanical aspect of modern compost methods pertain primarily to the shredding process that takes place prior to chemical decomposition. This merely increases the surface area of the composite material enhancing the bacterial decomposition process

Answer 6

If you mean that something is demonstrating plasticity, that would be a physical change.

If you mean that plastic (a substance) is being formed, that's a chemical change.

However, "plastic" itself is not really a change of any kind, so the best answer is "No."
