Answer:

HEY BUDDY,

GOOD AFTERNOON

Explanation:

This phenomenon of refreezing is known as regelation. Here, the melting point of the ice becomes lower than 0°C due to the applied pressure. This implies that at 0°C ice is converted into water and as soon as the pressure is removed the melting point is restored back to 0°C and the water is converted back to ice again.
