How could you set up an experiment to prove that burning a paper does not change its mass?

Answer 1

Weigh an empty non-flammable closed box and record its mass. Put a piece of paper with a large enough mass to be detected inside the closed box. Weigh the closed box with the paper inside it and record its mass.

How do we -{Light the paper on fire inside the closed box and wait until the paper is fully burned}?

Weigh the closed box with burned paper inside it and record its mass.

Subtract the box with ashes weight from the box with paper weight, and analyze the result(s).

Answer 2

When you burn it, some of the mass is released as a gas. If you were to burn the paper in a sealed glass cube, the gas would be captured and the mass would stay the same.

Because burning it releases some of the material that makes it up as gas. and even if you caught the material that escaped into the air in smoke and weighed that as well, it would still be lighter as some of the mass has been converted to energy.

Answer 3

The law of conservation of mass states that after a piece of paper has been burned, the products of the combustion (ash, gases, etc.) would have the same mass as the reactants (paper and oxygen).

Answer 4

yes, the mass is the same. The law of conservation of mass says what you start with is what you end with, so you always end with the same mass. it may not be in the same form as what you began with, but it's the same. when you burn paper you get ashes, smoke, and gases. when you add all three of those masses together you get the mass of the original piece of paper.

Answer 5

To prove that burning a paper does not change its mass, you could set up an experiment where you measure the mass of the paper before burning it, burn the paper completely, and then measure the mass of the ashes left behind. If the mass of the ashes is equal to the initial mass of the paper, it would suggest that the mass of the paper remained constant during the burning process.
