The correct answer is D. Affect the size, shape, and phase of a substance
Explanation:
In chemistry, a physical change occurs when a substance changes its state, and other features such as color or size without changing its structure, composition or properties as it occurs in chemical changes that involve a change in composition or formation of new substances. An example of this is water that changes its state to gas if it reaches its boiling point or to ice if the temperature is reduced. However, this only changes the size, shape, and phase of water without altering its composition. Also, this change is reversible. This implies, physical changes only "affect the size, shape, and phase of a substance".
