What is the difference between a physical property and a chemical property?

• A physical property can only be observed during a chemical reaction, while a chemical property can be observed without changing the substance.

• A physical property describes the ability of a substance to undergo a specific chemical change, while a chemical property describes the substance's appearance.

• A physical property can be observed without changing the substance's identity, while a chemical property can only be observed by changing the substance's identity.

• A physical property is always quantitative, while a chemical property is always qualitative.

Is density an extensive or intensive property? Justify your answer with reasoning.

• Density is an extensive property because it depends on the amount of substance present.

• Density is an intensive property because it does not depend on the amount of substance present.

• Density is neither extensive nor intensive because it varies with temperature.

• Density is both extensive and intensive because it can be measured in different ways.
