Endothermic

The ice has weaker forces of attraction between molecules than the liquid water

The strength of the forces between the molecules of both ice and liquid water are the same

The ice has stronger forces of attraction between molecules than the liquid water

Heat energy from the ice is released to the counter,decreasing the forces between molecules and increasing their temperature

Heat energy from the ice is released to the counter,increasing the forces between molecules and decreasing their temperature

Heat energy from the counter enters the ice,decreasing the forces between molecules and increasing their temperature
