Physical Properties in Chemistry

Robin Higgins explains physical properties in chemistry, which can be observed without changing the substance. She contrasts them with chemical properties, which require altering the chemical structure. The video covers intensive properties, which remain constant regardless of amount, and extensive properties, which change with quantity. Examples of physical properties include length, flexibility, melting point, color, shape, density, volume, and luster.

What is a physical property?

• A property that involves a change in temperature.

• A property that can only be observed by changing the chemical structure.

• A property that is only visible under a microscope.

• A property that can be observed without altering the substance.

Which of the following is an example of a chemical property?

• Length

• Color

• Burning a match

• Density

What is an intensive property?

• A property that involves a chemical reaction.

• A property that remains the same regardless of the amount.

• A property that is only applicable to metals.

• A property that changes with the amount of substance.

Which of the following is an extensive property?

• Conductivity

• Luster

• Color

• Mass

Which property is described as how shiny something is?

• Flexibility

• Luster

• Shape

• Volume

What happens to water when it melts?

• It becomes a different chemical.

• It remains chemically the same.

• It loses its physical properties.

• It gains new chemical properties.

Which of the following is NOT a physical property?

• Flexibility

• Melting point

• Combustibility

• Density

What is the significance of melting point in physical properties?

• It determines the color of a substance.

• It indicates a chemical change.

• It is a measure of how a substance reacts with water.

• It is a physical change that does not alter the chemical structure.

Which property is NOT affected by the amount of substance present?

• Volume

• Mass

• Shape

• Conductivity
