Physical and chemical change can have many positive effects on humans. The process of growth involves many reactions and visible changes, resulting in a stronger, more intelligent person.

Physical... The ice cream could eventually be returned to it's original form. Good question though, and remember that chemical changes are between two elements. Good luck (:
Chemical. Four good indicators of a chemical change are: # Change in Color # Change in Temperature # Creation of a gas # Creation of a precipitate These don't always indicate a chemical change, but are good guidelines if you are unsure.
Drying of leaves is a physical change because neither it changes its composition nor does it have any different properties from the original one.
It is a chemical change, the iron is being oxidized and forming rust. A good way to think about it is if you can undo it then it is a physical change. For example if you put salt in water, that is a physical change because you can boil off the water and get the salt back. Source: AP Chemistry
Physical changes can include changes in size, shape, or state, while chemical changes involve the formation of new substances. Good effects of physical changes can include creating new materials like paper from wood pulp, while good effects of chemical changes include producing new medicines through chemical reactions. Both types of changes can be used to create new products and materials for various applications.

yes No. Nothing changes in its chemical nature.
Hindi ko rin alam.. kaya nga nagtatanong eh ..
physical change, because the frozen rain can be turned back into rain (or water if you want to be exact) But a good example of a chemical reaction would be, you have the ingredients for a cake, you take those ingredients, mix and bake them, that would be a chemical reaction because it cannot be turned back into a cake

A physical change the chemical compounds remain the same in the change, in a chemical change the chemical compound changes. A good example is if you move a raw egg around in a pan, some of the egg may separate but it's still a raw egg. If you turn on the heat and cook the egg you are chemically changing the egg and it so no longer a raw egg.
