Question

part one: physical or chemical property? fill in the chart using the vocabulary words or phrases provided. vocabulary words boiling point ability to rust melting point brittleness reactivity with vinegar elasticity flammability density transparency ductility each word is used once. define the word when done! chemical property definition - the ability to burn - reacts with oxygen to produce rust physical property definition - the property of letting light pass through something

Explanation:

Step1: Identify Chemical Properties

Chemical properties involve changes in substance identity. Flammability (ability to burn) is a chemical property. Ability to rust (reacts with oxygen to rust) is chemical. Reactivity with vinegar (chemical reaction) is also chemical. So we assign:

• Flammability: Chemical Property (def: ability to burn)
• Ability to rust: Chemical Property (def: reacts with oxygen to rust)
• Reactivity with vinegar: Chemical Property (def: reacts with vinegar in a chemical change)

Step2: Identify Physical Properties

Physical properties are about appearance/state, no substance change. Transparency (lets light through) is physical. Boiling point (temp to boil), Melting point (temp to melt), Brittleness (breaks easily), Elasticity (stretches), Density (mass/volume), Ductility (stretches into wire) are physical. So:

• Transparency: Physical Property (def: lets light through)
• Boiling point: Physical Property (def: temp at which liquid boils)
• Melting point: Physical Property (def: temp at which solid melts)
• Brittleness: Physical Property (def: tendency to break)
• Elasticity: Physical Property (def: ability to stretch/return)
• Density: Physical Property (def: mass per unit volume)
• Ductility: Physical Property (def: ability to be drawn into wire)

Answer:

Chemical Properties Table:

Chemical Property	Definition
Ability to rust	Reacts with oxygen to produce rust
Reactivity with vinegar	Reacts with vinegar (chemical change)

Physical Properties Table:

Physical Property	Definition
Boiling point	Temperature at which a liquid boils
Melting point	Temperature at which a solid melts
Brittleness	Tendency to break easily
Elasticity	Ability to stretch and return to original shape
Density	Mass per unit volume ($\frac{\text{mass}}{\text{volume}}$)
Ductility	Ability to be drawn into a thin wire
