Water level after melting of ice.

Click For Summary

Discussion Overview

The discussion revolves around the question of water level changes when ice that is floating on water melts. Participants explore the implications of Archimedes' principle and the relationship between the volume of ice and the volume of water produced upon melting.

Discussion Character

  • Conceptual clarification, Debate/contested

Main Points Raised

  • Some participants assert that when ice melts, the water level must increase, questioning why it remains unchanged.
  • Another participant asks how the volume of the ice compares with the volume of the water produced when the ice melts.
  • A participant references Archimedes' principle, suggesting it may be relevant to understanding the situation.
  • One participant explains that when water turns to ice, it expands, and the amount that sticks above the water corresponds to the volume of water displaced. They argue that when the ice melts, it shrinks back to fit within the water level, resulting in no change in water level.

Areas of Agreement / Disagreement

Participants express differing views on whether the water level changes when ice melts, indicating a lack of consensus on the issue.

Contextual Notes

Some assumptions regarding the behavior of ice and water, as well as the application of Archimedes' principle, are not fully explored or defined, leaving room for further discussion.

When an ice melts on water, which was initially floating on it, the water level must get increased.
Why it remains unchanged??

How does the volume of the ice compare with the volume of the water produced when the ice melts?
 
Have you studied Archimedes' principle?
 
When water turns to ice, it grows. The amount of growth is exactly the amount that sticks up above the water. When it melts, it shrinks to fit exactly back inside the water level. So the water level doesn't change.
