10 examples of physical properties and chemical properties?

1. Color: The color of a substance is a physical property that can be observed without changing the substance's chemical composition. For example, gold is yellow, silver is white, and copper is reddish-brown.

2. Odor: The odor of a substance is a physical property that can be detected by the sense of smell. For example, gasoline has a strong odor, while vanilla extract has a sweet odor.

3. Taste: The taste of a substance is a physical property that can be detected by the sense of taste. For example, sugar tastes sweet, salt tastes salty, and lemon juice tastes sour.

4. Melting point: The melting point of a substance is the temperature at which it changes from a solid to a liquid. For example, the melting point of ice is 0 degrees Celsius, while the melting point of gold is 1064 degrees Celsius.

5. Boiling point: The boiling point of a substance is the temperature at which it changes from a liquid to a gas. For example, the boiling point of water is 100 degrees Celsius, while the boiling point of ethanol is 78.4 degrees Celsius.

6. Density: The density of a substance is its mass per unit volume. For example, the density of water is 1 gram per cubic centimeter, while the density of gold is 19.3 grams per cubic centimeter.

7. Solubility: The solubility of a substance is its ability to dissolve in a solvent. For example, sugar is soluble in water, while oil is not.

8. Conductivity: The conductivity of a substance is its ability to conduct electricity. For example, metals are good conductors of electricity, while rubber is a poor conductor of electricity.

9. Magnetic susceptibility: The magnetic susceptibility of a substance is its ability to be magnetized. For example, iron is a ferromagnetic material, which means that it is strongly attracted to magnets, while aluminum is a paramagnetic material, which means that it is weakly attracted to magnets.

10. Hardness: The hardness of a substance is its resistance to scratching. For example, diamond is the hardest substance known, while talc is the softest.

Chemical properties:

1. Reactivity: The reactivity of a substance is its tendency to undergo chemical reactions. For example, sodium is a highly reactive metal that reacts vigorously with water to produce hydrogen gas and sodium hydroxide.

2. Flammability: The flammability of a substance is its ability to burn. For example, gasoline is a flammable liquid, while water is not.

3. Corrosiveness: The corrosiveness of a substance is its ability to eat away at other materials. For example, hydrochloric acid is a corrosive liquid that can dissolve metals.

4. Toxicity: The toxicity of a substance is its ability to cause harm to living organisms. For example, arsenic is a toxic substance that can cause death if ingested.

5. Oxidizing ability: The oxidizing ability of a substance is its ability to cause other substances to lose electrons. For example, oxygen is a strong oxidizing agent that can cause iron to rust.

6. Reducing ability: The reducing ability of a substance is its ability to cause other substances to gain electrons. For example, hydrogen is a strong reducing agent that can cause copper oxide to be reduced to copper metal.

7. Acid-base properties: The acid-base properties of a substance are its ability to donate or accept protons. For example, hydrochloric acid is an acid that can donate protons, while sodium hydroxide is a base that can accept protons.

8. Salt formation: The salt formation properties of a substance are its ability to form salts when it reacts with acids or bases. For example, sodium chloride is a salt that is formed when sodium reacts with hydrochloric acid.

9. Complex formation: The complex formation properties of a substance are its ability to form complexes with other molecules or ions. For example, hemoglobin is a protein that forms a complex with oxygen.

10. Catalysis: The catalysis properties of a substance are its ability to speed up the rate of a chemical reaction without being consumed in the reaction. For example, enzymes are catalysts that speed up the rate of biochemical reactions.
