Conservation of Matter

Front

What happens to matter during a chemical reaction?

Back

Matter is neither created nor destroyed; it is converted from one form to another.

Front

What is the law of conservation of matter?

Back

The law states that the total mass of an isolated system remains constant, regardless of the processes acting inside the system.

Front

What is the relationship between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.

Front

How can we demonstrate the conservation of matter in a closed system?

Back

By measuring the mass of reactants before a reaction and the mass of products after the reaction, we can show that the total mass remains the same.

Front

What happens to the weight of a balloon as it collects gas?

Back

The weight reading on the scale stays the same because the gas is contained within the balloon.

Front

If 25 grams of sugar dissolves in 150 grams of water, what is the total weight of the solution?

Back

The total weight of the solution is 175 grams.

Front

What is the definition of matter?

Back

Matter is anything that has mass and takes up space.

Front

What evidence supports the conservation of matter in physical changes?

Back

The total weight of the substances before and after the change remains approximately the same.

Front

What is an example of matter being converted to gas?

Back

When flash paper burns, it converts to gas and dissipates into the air.

Front

What is the significance of measuring weight before and after a reaction?

Back

It helps to verify that matter is conserved during the reaction.
