RESEARCH METHODOLOGY

Detailed explanation-1: -Because salt particles make it harder for water particles to freeze back onto the ice, the ice that is in contact with dissolved salt melts faster. When the saltwater flows over the surface it melts the ice on its way, creating channels, like rivers, over the surface of the ice ball.

Detailed explanation-2: -Salt, baking soda, and sugar will all act to lower the freezing point of the ice, making it melt quicker than the untouched ice cube. Sand is another common substance that may be seen on the roadway.

Detailed explanation-3: -Salt water freezes at a lower temperature than the 32 degrees F at which freshwater freezes. The difference between the air temperature and the freezing point of salt water is bigger than the difference between the air temperature and the freezing point of freshwater. This makes the ice with salt on it melt faster.

Detailed explanation-4: -As an ice cube melts, its shape changes as it acquires the ability to flow. However, its composition does not change. Melting is an example of a physical change. A physical change is a change to a sample of matter in which some properties of the material change, but the identity of the matter does not.
