* Density, not weight, matters: "Heavier" implies more mass. What really matters is density, which is mass per unit volume. A liquid can be more dense than a solid, less dense, or even the same density.
* Examples:
* Water vs. Ice: Ice floats on water, meaning it's less dense.
* Mercury vs. Iron: Liquid mercury is denser than solid iron.
* Oil vs. Water: Oil floats on water, indicating it's less dense.
Why the Misconception?
The misconception likely stems from the fact that most common liquids are not denser than their solid counterparts. Think about water: it's a common liquid that expands when it freezes into ice. However, this isn't a universal rule.
In summary: It's incorrect to say that a liquid is always heavier than a solid. Density, the measure of mass per unit volume, is the key factor determining whether a liquid is heavier than a solid.
