Answer 1

Physical change involves a change in the form or state of matter, while chemical change involves a change in the chemical composition of a substance. Volume is an extensive property, while temperature, humidity, heat, and boiling point are intensive properties.

Step-by-step explanation:

In chemistry, physical change refers to a change in the form or state of matter without a change in its chemical composition. This means that the substance remains the same at the molecular level. Examples of physical changes include freezing water into ice or melting a cube of butter. On the other hand, chemical change refers to a change in the chemical composition of a substance, resulting in the formation of new substances with different properties. In a chemical change, the bonds between atoms are broken and new bonds are formed. Examples of chemical changes include burning wood to produce ash and smoke or rusting metal.

Classification of Physical Properties:

1. Extensive: Volume - because it depends on the amount of substance present.
2. Intensive: Temperature - because it does not depend on the amount of substance present.
3. Intensive: Humidity - because it does not depend on the amount of substance present.
4. Intensive: Heat - because it does not depend on the amount of substance present.
5. Intensive: Boiling point - because it does not depend on the amount of substance present.
