Worksheet on chemical vs physical properties and changes – Delving into the fascinating realm of chemical and physical properties and changes, this worksheet unveils a comprehensive understanding of these fundamental concepts in chemistry. Embarking on an educational journey, we will explore the distinct characteristics that define chemical and physical properties, unravel the intricacies of chemical and physical changes, and engage in thought-provoking exercises to solidify our grasp of these essential principles.
Chemical vs Physical Properties
Chemical properties describe the ability of a substance to undergo a chemical change, while physical properties describe the observable characteristics of a substance without changing its chemical composition.
Examples of chemical properties:flammability, reactivity with acids, toxicity
Examples of physical properties:color, density, melting point
| Chemical Property | Physical Property |
|---|---|
| Flammability | Color |
| Reactivity with acids | Density |
| Toxicity | Melting point |
Chemical vs Physical Changes
Chemical changes involve the rearrangement of atoms to form new substances, while physical changes do not alter the chemical composition of a substance.
Examples of chemical changes:burning, rusting, cooking
Examples of physical changes:melting, freezing, sublimation
- Chemical changes are irreversible, while physical changes are reversible.
- Chemical changes produce new substances, while physical changes do not.
- Chemical changes involve energy changes, while physical changes do not.

Popular Questions
What is the key difference between chemical and physical properties?
Chemical properties describe the ability of a substance to undergo chemical reactions, while physical properties describe observable characteristics that do not involve chemical changes.
Can physical changes be reversed?
Yes, physical changes are generally reversible, meaning the substance can return to its original form after the change.
What is an example of a chemical change?
Burning wood is an example of a chemical change, as it produces new substances (ashes and gases) with different properties than the original wood.
