Ice Melting in Water: Does the Water Level Change?

The video tutorial explores a classic buoyancy problem: what happens to the water level in a glass as a chunk of ice melts. The teacher guides students through understanding the forces acting on the ice, using a free body diagram, and applying equations to solve the problem. The key insight is that the water level remains the same because the mass of the ice equals the mass of the water it displaces. The video concludes with a visual demonstration and reinforces the concept that the density of water increases as ice melts, filling the space below the water line.

Explain why the water level remains the same as the ice melts.

How does the density of a substance change when it goes from ice to water?
