Question

1. check the box if the statement describes a chemical property or a physical property.

color
toxicity
ductility
flammability
reactivity
malleability
density
boiling point

Explanation:

• Color: A physical property as it can be observed without changing the substance's chemical composition.
• Toxicity: A chemical property as it relates to a substance's ability to cause harm (a chemical change or reaction in biological systems).
• Ductility: A physical property as it describes a substance's ability to be drawn into wires (a physical change).
• Flammability: A chemical property as it refers to a substance's ability to burn (a chemical reaction with oxygen).
• Reactivity: A chemical property as it pertains to how a substance interacts (reacts) with other substances.
• Malleability: A physical property as it is about a substance's ability to be hammered into sheets (a physical change).
• Density: A physical property as it is a ratio of mass to volume and can be measured without altering the chemical nature.
• Boiling point: A physical property as it is the temperature at which a substance changes from liquid to gas (a physical change).

Answer:

• color: Physical property
• toxicity: Chemical property
• ductility: Physical property
• flammability: Chemical property
• reactivity: Chemical property
• malleability: Physical property
• density: Physical property
• boiling point: Physical property
