Melting of ice: Ice melting into water is a physical change because it only involves a change in state from solid to liquid, without altering the chemical composition of water molecules.
Boiling of water: Water boiling into steam is a physical change as it involves the conversion of liquid water into water vapor, without any chemical reactions taking place.
Crumpling a piece of paper: Crumpling a piece of paper is a physical change because it only alters the shape and appearance of the paper without changing its chemical composition.
Freezing water: Freezing water into ice is a physical change as it involves the transformation of liquid water into a solid state without any alteration in the chemical properties of water.
Breaking a glass: Breaking a glass is a physical change because it involves the glass shattering into smaller pieces, changing its physical appearance but not its chemical composition.
Temporary changes in materials are often referred to as physical changes. These changes do not alter the chemical composition of the material and can usually be reversed by physical means. Examples include changes in state (e.g. melting, freezing) or changes in shape.
Chemical change examples include: when bleach reacts with dirt on a surface, forming new molecules; when vinegar and baking soda mix, producing carbon dioxide gas. Physical change examples include: when ice melts into water; when detergent dissolves in water.
Explain the difference between chemical change and physical change, and provide examples of each. Define chemical change and physical change, and provide examples to illustrate. Differentiate between chemical change and physical change, and give examples to clarify the distinction.
Temporary changes to a material are known as physical changes. These changes do not alter the chemical composition of the material but only its physical properties such as shape, size, or state.
Examples: density, hardness, boiling point, refractive index.

I can give you several sentences.He tried to think of an excuse to justify his bad behavior.Can you justify that action?"Justify me; open my mind to the things I can be." (from the Nate James song "Justify Me")suzan had to justify the amount of time she would give me for the test
Examples: density, hardness, boiling point, refractive index.
