Law of Conservation of Matter

Front

What is the Law of Conservation of Matter?

Back

The Law of Conservation of Matter states that matter cannot be created or destroyed in a closed system; it can only change forms.

What happens to the mass of leaves when they are burned?

Back

When leaves are burned, their mass is transformed into smoke and gas, but the total mass remains the same.

If a chemical reaction starts with 6 atoms of carbon (C), how many atoms of carbon (C) will be in the products?

Back

6 atoms of carbon (C) will be in the products, demonstrating that matter is conserved.

Front

What is an example of a physical change that demonstrates the Law of Conservation of Matter?

Back

Melting cheese is a physical change; the mass remains the same before and after melting.

Front

What is a chemical reaction?

Back

A chemical reaction is a process that involves the rearrangement of atoms to form new substances, while conserving mass.

Front

What is the significance of the mass of a closed system during a chemical reaction?

Back

The mass of a closed system remains constant during a chemical reaction, illustrating the Law of Conservation of Matter.

Front

What happens to the mass of a burning candle in a closed jar?

Back

The mass of the arrangement remains the same, even after the candle burns, as the matter is transformed into gases.

Front

What is an example of matter being transformed into gas?

Back

When leaves are burned, they release smoke and gases, demonstrating the transformation of solid matter into gas.

Front

What is the difference between a physical change and a chemical change?

Back

A physical change alters the form of a substance without changing its chemical composition, while a chemical change results in the formation of new substances.

Front

What is the role of atoms in the Law of Conservation of Matter?

Back

Atoms are rearranged during chemical reactions, but the total number of atoms remains constant, illustrating conservation of mass.
