Some physical characteristics of matter are shape, color, size, and temperature. An important physical property is the phase (or state) of matter. The three fundamental phases of matter are solid, liquid, and gas (figure 1.2. 1).
What Are the Characteristics of Matter?
In physics, matter is any substance that has mass and takes up space. All the everyday objects that we can see and touch are made of matter. In addition, all gases, liquids, and solids are made of matter.
Atoms and molecules are the smallest units of matter. They are so small that they can only be seen with a powerful microscope. Atoms are the basic units of all the elements in the periodic table.
A molecule is two or more atoms that are joined together. There are three major states of matter: solid, liquid, and gas. The state of a substance depends on how much energy is in the substance.
A solid has the least amount of energy, and a gas has the most. The physical properties of matter are used to describe matter. These properties include:
– Mass: the amount of matter in an object
– Volume: the amount of space an object takes up
– Density: the mass of an object divided by its volume
– Melting point: the temperature at which a solid turns into a liquid
– Boiling point:
the temperature at which a liquid turns into a gas The chemical properties of matter are used to describe how matter interacts with other matter. These
