can somebody explain to me whats the difference between physical and chemical properties of a substance?

Absolutely! I'd be happy to explain the difference between physical and chemical properties of a substance.
Physical properties:
Physical properties are characteristics of a substance that can be observed or measured without changing the substance's chemical composition. These properties describe the appearance, state, and behavior of the substance. Examples of physical properties include color, odor, density, melting point, boiling point, solubility, and conductivity.
To determine the physical properties of a substance, you can perform simple observations or use various measuring tools, such as a thermometer, balance, or ruler. You do not need to alter the substance on a molecular level to determine its physical properties.
Chemical properties:
Chemical properties, on the other hand, describe the behavior of a substance when it undergoes a chemical change or reaction. These properties relate to how a substance interacts with other substances, including its ability to undergo combustion, oxidation, corrosion, or decomposition. Examples of chemical properties include flammability, reactivity, acidity, and toxicity.
To examine the chemical properties of a substance, you would need to carry out experiments that involve altering the substance's molecular structure through chemical reactions. These experiments may involve introducing the substance to different reagents or subjecting it to heat or light.
In summary, physical properties describe observable characteristics of a substance without altering its chemical composition, while chemical properties describe how a substance interacts with other substances and undergoes chemical changes.
