volume of water increasing on freezing

|
|
glass is a bad conductor of heat
|
|
|
the bottle contracts on freezing

Explanation:
Detailed explanation-1: -So, a corked bottle full of water when frozen will break because the volume of water increases on freezing which puts pressure on the walls of the bottle so it will crack.
Detailed explanation-2: -The “stuff” (molecules) in water is more tightly packed than in ice, so water has greater density than ice. Don’t let the fact that ice is a solid fool you! As water freezes it expands. So, ice has more volume (it takes up more space, but has less density) than water.
Detailed explanation-3: -When disposable water bottles freeze or are exposed to heat (e.g. after being left in a car), chemicals may leach out of the container and into the water, increasing your cancer risk.
