SUMMARY

The discussion centers on the principle of buoyancy and displacement, specifically regarding the scenario of ice melting in a glass of water. When ice, which floats, melts, it does not cause the water level to rise because it displaces its own mass in water. This is supported by the principle that a floating object displaces an amount of water equal to its weight, not its volume. The analogy of a boat with a dense object illustrates that removing the object from the boat decreases the water level, confirming that the water surface remains unchanged when the ice melts.

PREREQUISITES
  • Understanding of Archimedes' principle
  • Basic knowledge of buoyancy
  • Familiarity with the concept of displacement
  • Knowledge of the properties of water and ice
NEXT STEPS

  • Study the physics of ice and water density
  • Examine real-world examples of displacement in fluids
USEFUL FOR

Students, educators, and anyone interested in physics, particularly those studying fluid dynamics and the principles of buoyancy and displacement.

When you take bottle of glass and fill it with some ice what happens to watersurface when ice has melted away? Does it rise surface? Or will it remain the same? Teacher spoke and demonstrated that and it didn't rise the surface. I believe in my eyes but is there any physical way to prove that surface doesn't rise up?

This is not homework it's only asked because I'm arguing about it with my friend and he doesn't believe me..

A floating object displaces its own mass in water. When it melts it is the same mass of water as it was when it was ice. Now it displaces its own volume as liquid water.

It might help if you think of another case. If a boat in a swimming pool has a relatively dense object in it the water level will drop if you take the object out of the boat and drop it into the water. The object was floating before and was displacing its mass of water while in the boat. When it is dropped into the water it displaces only the volume of the object.
