It's chemical because you can't get the pear back to a whole.
Pyrus communis is the wild pear.

All pear trees are called Pyrus followed by the species or Cultivar name.
Pear
You can't glue together a divided pear,if you want it to be valuable but it is not a chemical change..why?-The reason is that a chemical change is followed by entirely new product and what you have done is to seperate the pear molecules,it is still a pear!,and it is a physical change,and you are free to ask more question,because I understand that a pear has life..
It's chemical because you can't get the pear back to a whole.
No, cutting up a pear is a physical change, not a chemical reaction. Chemical reactions involve the breaking and forming of chemical bonds to create new substances, while cutting a pear only changes its physical appearance.
no, its physical
No it isn't, however, the oxidation of the organic material that occurs after the Pear has been cut, is a chemical reaction, it is called Redox.
no because you cannot really get it back to a whole pear.

A "prickly pear" is not actually a pear.
A pear is neither an acid nor a base in the same way that chemical compounds are classified. However, fruits like pears are generally considered to be acidic due to their pH level.
Prickly pear cacti protect themselves through a combination of physical and chemical defenses. They have sharp spines and glochids (tiny hair-like spines) that deter herbivores from feeding on them. Additionally, they can store water to survive dry conditions, making them resilient in arid environments. Some species also produce bitter or toxic compounds to further discourage animals from eating them.
A pear or a quince.
An Asian pear is a fruit from either species of pear from northeastern Asia, known for their crisp juicy texture - the apple pear or Chinese pear, or the Chinese white pear.
