It is a physical change because it is still grass. Nothing new has been made.
grass growing is a physical change.
Mowing is a mechanical process, not a chemical reaction.
Neither. It is a physical activity. See the link below for an explanation of physical and chemical properties.
Hence,the formation of dew and frost is a physical change.
Mowing the lawn is a physical change because it involves cutting the grass without altering its chemical composition. The grass remains the same substance; it is simply reduced in height. Physical changes affect the form or appearance of a material, while chemical changes involve a transformation into a different substance.
grass growing is a physical change.
Grass growing in a lawn is a physical change because the origonal substance still exists. :) good luck!
Grass growing in a lawn is a physical property because it is a natural process of the grass changing in size and shape without altering its chemical composition.
no
physical change
Mowing is a mechanical process, not a chemical reaction.
I would say a little of both. The consistensy of what grass is made of doesn't change,it enlarges, so it could be called a physical change. But to grow, the grass absorbes water and minerals and does photosynthesis, and creates large molecules, so this could be called chemical.
Lawn-mowing is a physical change, whereas the grass dying is chemical.
grass is a physical change.
It is a physical change because paper is still paper and its the same even if it has been cut. If the paper were say to get burned it would be chemical change because it is no longer paper and it has a different form.
it is a chemical change
Growing of hair is a biological process that involves physical changes in the cells of the hair follicles. It is not classified as a chemical change because the structure of the hair remains the same as it grows.
