Question

In science, the Law of Conservation of Matter tells us that matter cannot be created or destroyed, only _____ . This means that during both chemical changes and physical changes, the total amount of _____ stays the same, even though its _____ might change. For example, when you burn a piece of paper (a _____ change), it may seem like the paper disappears, but its atoms are actually transformed into ash and gases. Similarly, when you melt an ice cube (a _____ change), the water molecules remain the same; they just change from a solid to a liquid state. Whether matter undergoes a dramatic chemical change or a simple physical change, the total number of _____ involved doesn't increase or decrease. This fundamental principle helps scientists understand and explain many processes in our world, from cooking in the kitchen to complex industrial reactions.

Answer 1

In science, the Law of Conservation of Matter tells us that matter cannot be created or destroyed, only **transformed**. This means that during both chemical changes and physical changes, the total amount of **matter** stays the same, even though its **form** might change. For example, when you burn a piece of paper (a **chemical** change), it may seem like the paper disappears, but its atoms are actually transformed into ash and gases. Similarly, when you melt an ice cube (a **physical** change), the water molecules remain the same; they just change from a solid to a liquid state. Whether matter undergoes a dramatic chemical change or a simple physical change, the total number of **atoms** involved doesn't increase or decrease. This fundamental principle helps scientists understand and explain many processes in our world, from cooking in the kitchen to complex industrial reactions.
