What are the properties of matter?

Back

Properties of matter are characteristics that can be observed or measured, including physical properties (like color, mass, and volume) and chemical properties (like flammability and reactivity).

What is a chemical property?

Back

A chemical property is a characteristic of a substance that can only be observed during a chemical reaction, such as flammability or reactivity with acids.

Front

What is a physical property?

Back

A physical property is a characteristic of a substance that can be observed or measured without changing its identity, such as color, density, and melting point.

Front

What does flammability mean?

Back

Flammability refers to how easily a substance can catch fire and burn.

Front

What is the law of conservation of mass?

Back

The law of conservation of mass states that matter cannot be created nor destroyed in a chemical reaction; it can only be transformed.
