• decrease

• remain the same

Multiple Choice

Susan claims that the mass of a whole tree branch is more than the mass of all of the pieces of the tree branch after it has been cut up for firewood. Is she correct?

• No, the mass would be less because matter was added when it was cut.

• Yes, the mass would be more because matter was removed when it was cut.

• No, the mass would stay the same when the tree branch was changed physically.

Multiple Choice

Multiple Choice

Trey notices his basketball bounces so much better in the summer compared to the winter. He didn't add anymore air to the basketball, but it seems to be more full of air. Which explains why his observation is true?

• The warm temperatures in the summer caused the air molecules in his basketball to expand, making it fuller.

• Someone added air to his basketball in the summer, making it fuller.

• The cold temperatures in the winter caused the air molecules to expand, making it deflate.

• The warm temperatures in the summer caused the air molecules in his basketball to contract, making it fuller.

Multiple Choice
