Question

a ball of iron floats in mercury
true or false​

Answer 1

Answer:

true is the answer of this question

Answer 2

It is true that, a ball of iron floats in mercury.

• Floating or sinking of an object in a certain liquid, can be determined by comparing the density of the object with the density of that liquid.
• If the density of the object is greater than the density of the liquid, then the object will float in that liquid. And, if the density of the object is less than the density of the liquid, then the object will sink in that liquid.
• Now, density of mercury (liquid at room temperature) is greater than the density of iron (Density of mercury = 13.6 g/cm³ , and, Density of iron = 7.87 g/cm³). That's why, a iron ball will float in mercury.
