Properties of Matter and Reactions

Justin plans to build a rocket and explores the properties of matter to choose materials. He explains physical properties like color, mass, and magnetism, and chemical properties like reactivity and flammability. The video covers state changes, solubility, and the importance of understanding these properties for practical applications.

What is the main reason Justin wants to build a rocket?

• To explore the ocean

• To study the stars and planets

• To travel back in time

• To build a new house

Which of the following is NOT a physical property of matter?

• Color

• Reactivity

• Texture

• Volume

At what temperature does water freeze?

• 50 degrees Celsius

• 100 degrees Celsius

• 32 degrees Celsius

• 0 degrees Celsius

Which of the following materials is NOT soluble in water?

• Sugar

• Salt

• Sand

• Baking soda

Which metal is known for being magnetic?

• Gold

• Aluminum

• Iron

• Copper

What is a chemical property that describes how likely a substance is to react?

• Solubility

• Reactivity

• Density

• Magnetism

What happens to a sparkler when it reacts with fire?

• It becomes magnetic

• It dissolves

• It releases light and heat

• It melts

What is the term for the red, flaky substance that forms on some metals?

• Patina

• Tarnish

• Rust

• Mold

Which property describes how quickly a material will catch fire?

• Flammability

• Reactivity

• Magnetism

• Solubility

What is the main difference between physical and chemical properties?

• Both require a change in matter to be observed.

• Neither require a change in matter to be observed.

• Chemical properties can be observed without changing the matter's identity, while physical properties require a change in matter.

• Physical properties can be observed without changing the matter's identity, while chemical properties require a change in matter.
