There is more space between the water molecules if it is at a higher temperature, which is … So the faster you can add the needed energy to the sugar the faster is can dissolve so it dissolve faster in hot water. As salt is mixed into water, the charged water molecules interact with the charged salt molecules. This is why salt dissolves in water. ... Salt dissolves faster in hot water than in cold water. This increases the spaces between them so that there is room for more solute to dissolve. The crushed salt dissolve faster than table salt, since when the salt in crushed into small crystal, its surface area is increased therefore it dissolve faster as compared to table salt … substances dissolve faster in hot water. If you simply drop a lump of sugar in a glass filled with water, the dissolution will be notably slower, as water molecules can only come in contact with the particles on the surface. faster, causing the bonds holding it together to break faster, When salt is added to the ice bath (usually rock salt in ice cream making), it comes into contact with the thin layer of water on the surface of the melting ice. If you are doing a formal experiment, you should record the exact temperature of your water. 6 Answers. What about salt? Relevance.
