Physical Versus Chemical Properties of Matter Explained

This video tutorial from MooMoo Math and Science explains the difference between physical and chemical properties. Physical properties describe the physical characteristics of a substance, such as luster, hardness, ductility, malleability, conductivity, density, solubility, melting point, and boiling point. Chemical properties, on the other hand, become evident after a chemical reaction and include flammability, radioactivity, oxidizing ability, corrosiveness, toxicity, explosiveness, and pH level. The video concludes with a reminder to be kind.

What is the main difference between physical and chemical properties?

• Physical properties describe chemical reactions.

• Chemical properties are unrelated to matter.

• Chemical properties describe physical appearance.

• Physical properties describe physical characteristics, not chemical behavior.

Which of the following is a physical property?

• Radioactivity

• Toxicity

• Luster

• Flammability

What does the term 'ductile' refer to in physical properties?

• Ability to bend

• Ability to dissolve

• Ability to conduct electricity

• Ability to be pulled into a wire

At what point does a substance change from solid to liquid?

• Sublimation point

• Freezing point

• Melting point

• Boiling point

Which property describes how a substance reacts with an open flame?

• Corrosive

• Explosive

• Toxic

• Flammable

What does it mean if a substance is radioactive?

• It promotes combustion.

• It is non-reactive.

• It changes the nucleus of the atom.

• It is highly flammable.

Which chemical property involves the potential of hydrogen?

• pH

• Density

• Malleability

• Solubility

What is an oxidizer?

• A substance that promotes combustion

• A substance that is non-reactive

• A substance that dissolves in water

• A substance that is shiny

Which property is associated with the ability to cause health effects?

• Malleable

• Explosive

• Toxic

• Conductive

What is the key takeaway message from the video?

• Always focus on chemical properties.

• Physical properties are more important.

• Science is difficult to understand.

• Kindness multiplies kindness.
