Answer 2

Answer:

The reason for a physical change to be named as such is that the:

1. change occurs only in physical properties
2. transfer of energy takes place
3. It is a reversible change

Explanation:

1. A physical change to a sample of matter occurs when some of the material’s  physical characteristics change but the matter’s identity does not.
2. The example of physical change are change of state of matter, change in colour, odour etc. During physical change, molecules rearrange themselves without affecting the internal composition.
3. Physical changes in a substance do not form new substances, these reactions are reversible and the change is temporary.
4. When physical changes occur, they are generally accompanied by a transfer of energy. The law of conservation of energy states that in any physical process, energy is neither created nor destroyed.

Hence the option D) All of the above is correct.
