What is the most basic way to describe a change in matter?
"learn about melting, soldification, vaporization, condensation, sublimation, deposition"
Learning objective:
Matter can change from one form to another. Examples: gas to liquid, liquid to solid. When matter changes form, its properties can change too. For example, water can be a solid (ice) or a liquid. Energy is required for changes in matter to occur. Heat, light, and electricity are all forms of energy.
Changes in Matter
Matter is made up of tiny particles that are in constant motion. This is called the particle theory. Matter can be changed from one form to another. This is called a physical change. Matter can also change into a completely different substance. This is called a chemical change.
Concepts:
Matter can be converted from one form to another through processes like burning, freezing, or melting. Matter is made up of tiny particles called atoms and molecules that are constantly in motion. Atoms can be combined and rearranged in an infinite number of ways to create different substances.
