Chemistry Quiz: Physical and Chemical Properties

What are the physical properties of matter?

• Velocity, acceleration, force, energy

• Taste, sound, weight, volume

• Transparency, flexibility, hardness, shape

• Color, odor, density, melting point, boiling point, and conductivity

Explain the difference between intensive and extensive physical properties of matter.

• Intensive properties are only applicable to liquids, while extensive properties are only applicable to solids.

• Intensive properties change with temperature, while extensive properties remain constant.

• Intensive properties depend on the amount of substance, while extensive properties do not depend on the amount of substance.

• Intensive properties do not depend on the amount of substance, while extensive properties do depend on the amount of substance.

What are the chemical properties of matter?

• State of the matter

• Ability to conduct electricity

• Color of the matter

• Ability to undergo chemical reactions and form new substances

How do chemical properties of matter differ from physical properties?

• Chemical properties and physical properties are the same and can be used interchangeably

• Chemical properties involve the ability of a substance to undergo a chemical change, while physical properties involve characteristics that can be observed or measured without changing the substance's composition.

• Chemical properties can be observed without changing the substance's composition, while physical properties involve the ability of a substance to undergo a chemical change

• Chemical properties are only relevant in a laboratory setting, while physical properties are relevant in everyday life

Give an example of a change in physical properties of matter.

• Water freezing

• Salt dissolving in water

• Wood burning

• Iron rusting

Describe how the melting of ice is a change in physical properties.

• It changes from a gas state to a solid state without changing its chemical composition.

• It changes from a liquid state to a solid state without changing its chemical composition.

• It changes from a solid state to a liquid state without changing its chemical composition.

• It changes from a solid state to a gas state without changing its chemical composition.

Explain how the rusting of iron is a change in chemical properties.

• The rusting of iron is a change in chemical properties because it involves a chemical reaction that results in the formation of a new substance (iron oxide) with different properties.

• The rusting of iron is a change in chemical properties because it involves a change in color.

• The rusting of iron is a change in chemical properties because it involves a change in size.

• The rusting of iron is a change in chemical properties because it involves a change in shape.

What are elements, compounds, mixtures, and pure substances?

• Mixtures are pure substances made up of only one type of atom.

• Compounds are combinations of two or more substances that are not chemically bonded.

• Elements are pure substances made up of only one type of atom. Compounds are substances made up of two or more different types of atoms chemically bonded together. Mixtures are combinations of two or more substances that are not chemically bonded. Pure substances are either elements or compounds.

• Elements are substances made up of two or more different types of atoms chemically bonded together.

Differentiate between an element and a compound.

• An element is a mixture of different types of atoms, while a compound is a pure substance made up of only one type of atom.

• An element is a pure substance made up of only one type of atom, while a compound is a substance made up of two or more different types of atoms chemically bonded together.

• An element and a compound are both made up of the same type of atoms.

• An element is made up of two or more different types of atoms, while a compound is made up of only one type of atom.
