Question

why does ice float when it is placed in liquid water? because ice is much denser than water because the ice has a greater weight than water because the density of ice is less than water because the density of ice and water are the same

Explanation:

To determine why ice floats in liquid water, we use the principle of buoyancy: an object floats in a fluid if its density is less than the fluid's density.

• The first option is incorrect because ice is less dense (not more dense) than water.
• The second option is incorrect because weight depends on mass and gravity; a small piece of ice can have less weight than a large volume of water, and weight alone doesn’t determine floating (density does).
• The fourth option is incorrect because ice and water do not have the same density (ice is less dense).
• The third option is correct: ice floats because its density is less than that of liquid water.

Answer:

because the density of ice is less than water
