Question

a corked bottle full of water when frozen will break because.

• A. The volume of water increases on freezing
• B. The volume of water decreases on freezing
• C. The bottle contracts on freezing
• D. Glass is a bad conductor of heat

Answer 1

The correct option is A The volume of water increases on freezing

A corked bottle of water on being frozen at $0^{\circ }$ undergoes anomalous expansion of water between $4^{\circ }$ and $0^{\circ }$ wherein density of water increases on cooling , causing expansion due to orderly hydrogen bonding, this increasing volume cracks the bottle.

$Density=\frac{Mass}{Volume}$

$\Rightarrow D\propto \frac{1}{V}$

$\Rightarrow D\uparrow \Rightarrow V\downarrow$
