Physical Properties are characteristics of a substance that can be observed and measured without changing the identity of a substance. For example, a physical property of gold is that it is malleable (ability to bend) and has a lasting shine.

Question

Chemical Properties are a characteristic or behavior of a substance that may be observed when it undergoes a chemical change or reaction resulting in a new substance . For example, flammability is a chemical property because in order to observe whether wood is flammable a chemical reaction occurs and creates new substances (carbon dioxide gas, ash, etc.).

IMPORTANT NOTES:

Physical properties can typically be observed just using the senses like sight.
Chemical properties can be observed without the creation of a new substance. For example, if you light gold on fire it will not burn. Flammability, or the gold's lack of flammability, is still a chemical property.
It does not matter how much of a substance is present, the physical and chemical properties will still be the same. For example, whether you have 1 gold coin or 10 gold bars - the gold is still shiny (physical property) but not flammable (chemical property).
Chemical changes describe when one substance changes into an entirely new substance with different chemical properties. For example, when you light wood on fire it turns into ash and smoke. Ash and smoke have different properties than the original wood.
Physical changes describe when a substance undergoes a change in a physical property but no new substance has been created. For example, when you tear a piece of paper in half, a physical property (size) was changed but the properties of the paper stayed the same.
For each of the following properties, indicate whether it is a chemical or physical property by selecting the correct column.

Answer 1

Here is the classification of each property into the appropriate categories:

| Chemical Property | Physical Property | |---------------------------|--------------------------| | | Luster | | | Malleability | | Flammability | | | Radioactivity | | | Ability to oxidize | | | Toxicity | | | | Density | | | Color | | | Conductivity | | | Mass |

Final Classification:

• Luster: Physical Property
• Malleability: Physical Property
• Flammability: Chemical Property
• Radioactivity: Chemical Property
• Density: Physical Property
• Color: Physical Property
• Ability to oxidize: Chemical Property
• Toxicity: Chemical Property
• Conductivity: Physical Property
• Mass: Physical Property
