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.
A physical change occurs.
Yes, pure water is an example of homogeneous matter as long as it's one phase.
When matter changes from one state to another, heat is either absorbed or released. For example, when ice melts, heat is absorbed from the surroundings causing the surrounding area to cool down. On the other hand, when water evaporates, heat is released into the surroundings.
One way to determine if a change is physical is if the substance changes its form or appearance without altering its chemical composition. For example, melting or freezing a substance, dissolving it in water, or changing its state of matter are all physical changes.
Physical changes.
One example of a process that does not involve the movement of matter is a phase change, such as solidification or condensation, where the state of a substance changes without the molecules themselves moving to a new location.
When a substance changes from one state of matter to another it is called changing its state. Temperature changes are usually the main cause of this change.

the faces of matter is what you called the one of the subject in science...but pls give me one example of faces of matter
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.

A phase transition.
