Conservation of Matter

Front

What does the Law of Conservation of Matter state?

Back

The Law of Conservation of Matter states that matter cannot be created or destroyed in an isolated system.

Front

If an object weighs 50 grams and is cut in half, what is the weight of each half?

Back

Each half would weigh 25 grams, demonstrating that the total mass remains the same.

Front

What happens to the total mass of a substance when it undergoes a physical change?

Back

The total mass remains the same during a physical change.

Front

How does the Law of Conservation of Matter apply to chemical reactions?

Back

In a chemical reaction, the total mass of the reactants equals the total mass of the products.

Front

What is an example of matter being transformed?

Back

An example is water boiling into steam; the water changes state but the total mass remains the same.

Front

If 10 grams of salt is added to 200 grams of water, what is the total mass of the solution?

Back

The total mass of the solution would be 210 grams.

Front

What is the significance of the Law of Conservation of Matter in scientific experiments?

Back

It ensures that mass is conserved, allowing scientists to predict the outcomes of reactions.

Front

Can matter be created or destroyed in a closed system?

Back

No, in a closed system, matter cannot be created or destroyed.

Front

What is the mass of a mixture if 5 grams of sugar is mixed with 15 grams of flour?

Back

The mass of the mixture would be 20 grams.

Front

What is an example of a physical change that illustrates the conservation of matter?

Back

Crushing a can; the mass remains the same before and after crushing.
