Question

Water at ${10}^{\circ }C$ or Water at $4^{\circ }C$. Which has more volume?

• A. Both have same volume
• B. Water at ${10}^{\circ }C$
• C. Water at $4^{\circ }C$
• D. None of the above

Answer 1

The correct option is B Water at ${10}^{\circ }C$

$4^o$ C turns out to be the temperature at which liquid water has the highest density. If you heat it or cool it, it will expand. The expansion of water when you cool it to lower temperatures is unusual, since most liquids contract when they're cooled.
