Question
Explain, why does a glass bottle completely filled with water and tightly capped burst when placed in a freezer?
✓
Answer
A glass bottle completely filled with water and closed tightly is likely to burst in the freezer of refrigerator because water changes into ice and its volume increases. Since water when cooled from $4^{\circ} C$ to $0^{\circ} C$ expands. Thus, exerts large pressure and glass bottle bursts.
