Exploring Physical and Chemical Properties

What is the main objective of this lesson?

• To learn about chemical equations

• To discuss the periodic table

• To explain the history of chemistry

• To define and give examples of physical and chemical properties

Which of the following is a physical property?

• Acidity

• Density

• Flammability

• Reactivity

Which of the following best describes a physical property?

• A property that involves a chemical reaction

• A property that can be observed without altering the substance

• A property that changes the substance's chemical structure

• A property that measures the acidity of a substance

What does malleability refer to?

• The ability to conduct electricity

• The ability to dissolve in water

• The ability to bend without breaking

• The ability to change color

Which of the following is NOT a physical property?

• Acidity

• Solubility

• Density

• Conductivity

What is the significance of state changes in physical properties?

• They always involve a change in color

• They are not considered physical properties

• They indicate a chemical reaction

• They can be measured without changing the substance

Why can color and odor be tricky as physical properties?

• They are always chemical properties

• They can sometimes be influenced by chemical changes

• They are not measurable

• They do not change with state

What is a chemical property?

• A property that can be observed without changing the substance

• A property that is observed during a chemical reaction

• A property that describes the color of a substance

• A property that measures the mass of a substance

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

• Conductivity

• Malleability

• Density

• Flammability

What does reactivity refer to in chemical properties?

• The ability to conduct electricity

• The ability to change color

• The ability to react with other substances

• The ability to dissolve in water
