Vedclass · Answer

(A) When two ice cubes are pressed together,the pressure applied lowers the melting point of ice at the contact surface,causing a thin layer of ice to melt into water. Once the pressure is released,the water refreezes because the temperature is below $0 \ ^\circ C$. This process is known as regelation. The formation of hydrogen bonds between the water molecules in the refrozen layer acts as the primary force holding the two ice cubes together.

When two ice cubes are pressed together,they join to form a single cube. Which of the following forces is responsible for holding them together?
