Question

choose the correct description for each of the properties below:
dropdown density
dropdown flammability
dropdown solubility in water
dropdown reactivity with water
dropdown melting point
dropdown color
dropdown odor
options for dropdown (shown for odor): physical property, chemical property
button: done

Explanation:

• Density: A physical property as it can be measured without changing the substance's chemical identity.
• Flammability: A chemical property because it describes a substance's ability to undergo combustion (a chemical reaction).
• Solubility in water: A physical property as it involves the ability to dissolve (a physical process, no new substance formed).
• Reactivity with water: A chemical property as it describes how a substance reacts with water (a chemical change occurs).
• Melting point: A physical property as it is the temperature at which a substance changes state (physical change).
• Color: A physical property as it is an observable characteristic without altering the substance's chemistry.
• Odor: A physical property as it is a sensory characteristic of a substance without chemical change.

Answer:

• density: physical property
• flammability: chemical property
• solubility in water: physical property
• reactivity with water: chemical property
• melting point: physical property
• color: physical property
• odor: physical property
