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?

Question

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 2 grams.
D.
The sum of the mass of all the pieces of paper is less than 2 grams.

Answer 1

The correct statement is:

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

When Cynthia tears the sheet of paper into smaller pieces, the total mass remains the same. The mass of the original sheet of paper (2 grams) is conserved, regardless of how many pieces it is torn into. Thus, the total mass of all the pieces combined will still equal 2 grams.
