1. Melting is the change from the liquid state to the solid state. TRUE FALSE
2. During the melting of ice, mass does not vary because the number of water molecules does not change. TRUE FALSE
3. During the solidification of water, the volume decreases because water molecules become more closely packed. TRUE FALSE
4. During the boiling of water, the number of water molecules decreases. TRUE FALSE
5. During the melting of paraffin, mass does not vary, and volume increases 🕯️. TRUE FALSE
6. In general, molecules are more closely packed in the solid state than in the liquid state. TRUE FALSE
7. Finally, during a change of state, the arrangement of molecules changes. TRUE FALSE
