Question

Cynthia is holding a sheet of paper that has a mass of 2 grams. She tears the sheet of paper into many small pieces. Which of the following is true?

a.Each piece of paper has a mass of 2 grams.
b.The sum of the mass of all the pieces of paper is more than 2 grams.
c.The sum of the mass of all the pieces of paper is less than 2 grams.
d.The sum of the mass of all the pieces of paper is 2 grams.

Answer 1

The answer is C The sum of the mass of all the pieces of paper is 2 grams

Because, matter cannot be created or destroyed. The mass of a substance remains constant whether it is together or in parts. Therefore, the sum of the mass of all the pieces of paper must equal the mass of the whole sheet of paper: 2 grams.

Answer 2

The answer is D. The sum of the mass of all the pieces of paper is 2 grams. Hope this helped! Good luck! :)
