It is a physical change because it is still grass. Nothing new has been made.

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 is a mechanical process, not a chemical reaction.

Grass growing in a lawn is a physical change because the origonal substance still exists. :) good luck!

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.
A tree growing is a chemical change because the chemical reaction that happens in the trees cells causes the carbon dioxide and water to become sugar (food) for the plant to grow and oxygen it can "exhale" much like we exhale carbon dioxide.
No: its a physical changeAdded correction:It is chemical because you can not simply revert it (newly grown hair) back to its original compounds like keratine.Hair (newly grown) is a product of many (bio)chemical synthesis reactions.It is much the same as growing grass or trees or even animals and humans.
Lawn-mowing is a physical change, whereas the grass dying is chemical.

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.
Neither. It is a physical activity. See the link below for an explanation of physical and chemical properties.
