Possible indicators are:
- new compounds are obtained
- a change of phase may be possible
- change of color
- change of odor
- change of temperature
- change of viscosity
- change of pH
etc.
When matter undergoes a chemical change, the composition of the matter changes. When matter undergoes a physical change, composition of the matter remains the same.
Two types of changes in matter are physical changes and chemical changes. Physical changes involve a change in appearance, such as a change in shape or state, without forming new substances. Chemical changes involve a rearrangement of atoms to form new substances with different chemical properties.
Matter can undergo chemical changes when its composition is altered through chemical reactions. Chemical changes result in the formation of new substances with different properties than the original matter.
Matter can undergo physical changes, such as changes in state (solid, liquid, gas) or shape, without altering its chemical composition. It can also go through chemical changes, resulting in new substances with different properties due to rearrangement of atoms or breaking of chemical bonds. Additionally, matter can experience nuclear changes, like radioactive decay, where the nucleus of an atom changes leading to the formation of different elements.
a physical change is the form of matter but not in its chemical identity or is when the state or shape of matter is changed.physical change is reversable or temporary while a chemical is permenent or cannot be reversed.a chemical change is a change in which one or more kinds of matter are transformed into a new kind of matter.
Four forms of energy related to change in matter are thermal (heat) energy, chemical energy, nuclear energy, and electrical energy. These forms of energy can cause physical or chemical changes in matter by providing the necessary energy for these changes to occur.

chemical change = chemical reaction. ( the composition of matter always changes). In a chemical change the matter in one thing changes, for example you will know a chemical change has occurred when the color or odor has changes or when a new gas is given off.

Physical change, if it changes in a way to be seen, or chemical change, which if the change can not be seen
The two types of changes in matter that it goes through is physical change and chemical change... trust me, we are learning this at school.
It is a physical change. All phase changes are physical, not chemical. The chemical composition of water does not change when it changes from a liquid to a gas, or for that matter, to a solid.

The composition of matter changes during a chemical change as new substances are formed with different chemical properties. In contrast, the composition of matter remains the same during a physical change, with only the physical state or appearance of the substance being altered.
