About - What Makes Ice Melt Fastest?

Conclusion. Salt and sugar both causes freezing point depression, therefore making the ice melt faster, however salt is more effective as salt dissolves into two components and creates more interference in preventing water from freezing. Sand melts ice by absorbing heat which will bring it to a higher temperature than ice, causing it to melt.
