Question

Quizplus · Accepted Answer

When the ice cube melts, the water it turns into will occupy less volume than the ice did, because ice is less dense than water. However, the pieces of iron, being denser than water, will displace more water when they are submerged in the ice than when they are submerged in water after the ice has melted. This means the overall water level will fall.
