Question

Name the phenomenon responsible for cracking of plastic water bottle which was freezed​

Answer 1

Explanation:

Plastic will stretch around the ice. ... When it becomes ice, its volume expands a lot, since the density of ice is much lower than that of water. So do not fill any bottle completely with water before you put it is the freezer. The bottle will burst - nothing is stronger than the force of expanding water.

Answer 2

Answer:

You can argue that the expansion of the water starts at 4°C so even before ice is formed the liquid water will expands between 4 and 0°C, and the bottle may crack from that little bit expansion.
