A metallic wire is placed over an ice slab and is observed to pass through it without breaking the slab. What phenomenon allows the wire to pass through the ice?
A
Increased pressure lowers the melting point of ice under the wire.
B
The wire conducts heat, melting the ice directly beneath it.
C
Ice has a lower density than water, allowing the wire to pass.
D
The ice slab is not in thermal equilibrium, causing it to melt unevenly.
Correct Answer
Option A
Detailed Explanation
The pressure exerted by the wire lowers the melting point of ice beneath it, allowing the wire to pass through as the ice refreezes above it.
