1. Mass: Matter has mass, which is a measure of its inertia (resistance to change in motion) and the amount of matter it contains.
2. Volume: Matter occupies space, meaning it has volume. This refers to the amount of three-dimensional space it takes up.
These two characteristics are fundamental because they define what matter *is* and how it interacts with the world. However, matter has many other properties, including:
* Density: The ratio of mass to volume.
* State: Solid, liquid, gas, or plasma.
* Temperature: A measure of the average kinetic energy of its particles.
* Composition: The types and proportions of elements or compounds present.
* Chemical reactivity: How readily it reacts with other substances.
* Color: The wavelengths of light it absorbs and reflects.
* Texture: How it feels to the touch.
And many more!
