Question

Write a scientific reason.

Even if the wire moves through the ice slab, the ice slab does not break.

Answer 1

• Melting under pressure: The thin wire exerts high pressure on the ice directly beneath it. This increased pressure lowers the melting point of the ice, causing it to melt into liquid water.
• The wire moves: The wire easily passes down through this thin layer of liquid water.
• Instant refreezing: As soon as the wire moves past, the pressure on the water directly above it is removed. The melting point returns to normal (0°C), and that water instantly refreezes back into solid ice.
