An Introduction to Phase – State of Matter ;
The three phases of matter are solid, liquid, and gas. In a solid, the atoms are close together and held in place by strong forces. In a liquid, the atoms are still close together but are able to move around each other. In a gas, the atoms are far apart and move around freely.
The phase of a substance depends on the strength of the forces between the atoms. In a solid, the atoms are held in place by strong forces and cannot move around. In a liquid, the atoms are held together by weaker forces and can move around. In a gas, the atoms are held together by the weakest forces and can move around freely.
States of Matter Diagram
The states of matter are solid, liquid, gas, and plasma.
The diagram shows the states of matter in order from the most dense to the least dense. Solids are the most dense, followed by liquids, gases, and then plasma.
What is Phase in Chemistry
Phase is the physical state of matter. Matter can exist in three main phases: solid, liquid, and gas.
Phases of Matter
Solid: A solid has a definite shape and a definite volume. The atoms or molecules are close together and held rigidly in place.
Liquid: A liquid has a definite volume but no definite shape. The atoms or molecules are close together but not held rigidly in place.
Gas: A gas has neither a definite shape nor a definite volume. The atoms or molecules are far apart and move freely.
