Question

A full bottle of water was left outside overnight in freezing temperatures, causing the bottle to crack. No mass was added or removed from the bottle. Which property of water caused the crack? A. Solid water is more cohesive than liquid water. B. Solid water has lower surface tension than liquid water. C. Solid water is less dense than liquid water. D. Solid water is less adhesive than liquid water.

Answer 1

Answer:The correct answer is option C.

Explanation;

Water has unique property that is, it expands on freezing.Which is the reason for less density of ice than water. The cracking of the bottle was due to the expansion of water (present inside the bottle) on freezing.

Generally, density is inversely proportional to the volume of the substance.

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

$Density\propto \frac{1}{Volume}$

As we know ,that water expands on freezing which means that volume increases. And with increase in volume of density decreases.

Hence, the correct answer is option C.
