density mass shape volume
I gave my students this multiple choice question: Two identical containers each hold one liter of water. One container is kept at room temperature as a liquid. The other container is placed in a freezer and kept as a solid. Which property is most likely to be the same in both states of matter?

Only one answer is correct among these 4 choices:
- density
- mass
- shape
- volume

Could you tell me which one is correct?

mass
