What are the common properties of solid material?
A solid has a definite shape and does not change easily. For example, wood, plastic, rocks or steel would be considered solids. The molecules of a liquid move freely past each other. Liquids flow or pour, and must be kept in containers, take the shape of the container, and have a flat level surface.
What are the physical and chemical properties of solid?
Solid is distinguished by a fixed structure. Its shape and volume do not change. In a solid, atoms are tightly packed together in a fixed arrangement. Liquid is distinguished by its malleable shape (is able to form into the shape of its container), but constant volume.
What are the properties of a solid liquid and gas?
There are three common states of matter:
- Solids – relatively rigid, definite volume and shape. In a solid, the atoms and molecules are attached to each other.
- Liquids – definite volume but able to change shape by flowing. In a liquid, the atoms and molecules are loosely bonded.
- Gases – no definite volume or shape.
Why is it important to know the properties of solid?
It’s important for scientists to know the properties of matter because all things are made up of matter. The main phases of matter are solid, liquid, and gas. Most matter is able to be all of these phases depending on their physical characteristics. More importantly, scientists work with many different types of matter.
