Is cutting grasss a chemical or physical change?

Answer 1

I suppose you could make the point that any physical change to a living thing results in a chemical change of some type within the organism. In fact, at a molecular level, any physical change in any object would result in a chemical change. You'll have to accept this until you study quantum physics.

Answer 2

The answer to give your teacher should be "physical". However, both chemical and physical changes occur. For example, the oxidation of the lymph that oozes out the cut leaves and darkens is a chemical process.

Answer 3

It's a physical change. Cutting on the macroscopic scale is always a physical change. However, that's not to say that grass might not have a chemical response to being cut like that.

Answer 4

This is a physical change. The cutting does stimulate the grass to grow. The link below has a lot of information on turf grass.

Answer 5

Both, if done correctly. The grass is physically cut. However, if mulched, the clippings work their way into the ground and decompose, which is a chemical process, returning nutrients to the soil and breaking down thatch.

Answer 6

It is a physical change. It does not react or form a new type of object after being cut.

Answer 7

Physical change.

The grass might look different, but the chemical composition wouldn't have changed by just cutting of it (grass).

Answer 8

physical - you change the physical nature of it but it's chemical make-up is the same.

Answer 9

physical changes because you are changing its physical appearence

Answer 10

physical change
