Water has a lower freezing point than ice, so when exposed to water, ice will start to melt. The water molecules transfer heat to the ice, causing its solid structure to break down and transition to a liquid state. This process continues until the ice has completely melted and becomes water.
Ice has a greater cooling effect than cold water, as it absorbs more heat from its surroundings in order to melt and reach the same temperature as the water. Cold water, on the other hand, will only cool down the surrounding area until it reaches thermal equilibrium.
When dry ice is put in water, it sublimates, turning from a solid directly into carbon dioxide gas. This creates a bubbling effect as the gas is released, and the water may appear to boil. The combination of dry ice and water can also create a foggy or misty effect due to the rapid cooling of the surrounding air.
Baking soda does not have a significant effect on melting ice. It can lower the freezing point of water slightly when sprinkled on ice, but it is not as effective as salt or other ice-melting agents.
Water is more effective in extinguishing fires than ice. When water is applied to a fire, it absorbs heat and cools the burning material, helping to stop the combustion process. Ice could melt into water and achieve the same effect, but using ice directly on a fire may not be as practical or efficient.
Rock salt lowers the freezing point of water, causing the ice to melt. This melting process requires energy, which is absorbed from the surroundings, resulting in a cooling effect.
