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

Answer 1

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

When Cynthia tears the sheet of paper, the total mass remains the same because mass is conserved. The individual pieces may be smaller, but together they still add up to the original mass of 2 grams.
