Law Of Conservation Of Matter Definition
The Law of Conservation of Matter tells us that the amount of matter stays the same even when a substance changes form. For example, sugar dissolving in water changes form without matter loss.

Conservation of Matter
Fun Facts
- Ice melting does not change its mass because matter is conserved.
- Sometimes it may seem that matter disappears during a science experiment, but it is only changing form because matter cannot be magically created or destroyed.
- Dry ice turns into gas in a sealed flask, changing form but conserving matter.
Why Do We Need To Know About Law Of Conservation Of Matter
Learning about the law of conservation of matter helps you see how things change form but don’t disappear. For example, in cooking, knowing that sugar dissolves in water but doesn’t go away helps when making recipes. In environmental science, understanding that burning things turns them into gases helps with controlling pollution.
This idea is useful in real life. For example, knowing that the ‘smoke’ from dry ice is actually carbon dioxide changing from solid to gas helps keep food fresh during shipping. Also, realizing that bread rises because of gas bubbles, not because it gets more matter, is important for baking. These examples show how this law is used in different jobs to solve problems and create new things.
