What happens when a chemical property is observed?

Back

When a chemical property is observed, a new substance is formed with different properties.

What are some examples of physical properties?

Back

Examples of physical properties include color, density, mass, volume, and state of matter (solid, liquid, gas).

What are some examples of chemical properties?

Back

Examples of chemical properties include acidity, reactivity with water, and the ability to oxidize.

Front

How can you identify a physical change?

Back

A physical change can be identified if the substance's identity remains the same, such as melting ice into water.

Front

How can you identify a chemical change?

Back

A chemical change can be identified if a new substance is formed, such as when vinegar reacts with baking soda to produce carbon dioxide.
