Small, continuous sips of warm water.
it would melt.
No, because gelatin is meant to be hardened but then soft at the same time, so if you bake it, it would melt.
Gelatin is the real term for Jell-O, if that's what you mean. It does melt, because the process of making it starts with liquid.
Yes.
Gelatin form a gel when mixed with water.
To make unflavored gelatin, you can dissolve gelatin powder in hot water and then let it cool and set.
The boiling point of water will increase if gelatin will be added to the water. The reason for this is because gelatin adds to the concentration of the liquid resulting to higher boiling point.
To make jello from gelatin, you need to dissolve gelatin in hot water, add cold water and any desired flavorings, then refrigerate until set.
Blooming gelatin is just the process of soaking it in water before adding it to other ingredients - it helps the gelatin to dissolve evenly. To bloom gelatin leaves, place as many as you require in a bowl of cold water and leave for 4-5 minutes. Then remove the gelatin and place into the warm liquid which requires the gelling agent. To bloom gelatin powder, pour the gelatin onto the surface of a small cup of warm water. DO NOT STIR YET! Leave it for 5 minutes to soak and soften, then stir the liquid to combine the gelatin. (The purpose of not stirring immediately is because this can form lumps.)
A change in medium water to Gelatin would affect the rate of diffusion dramatically. The change from water to gelatin would slow down the rate of diffusion.
Mentos candies do not actually melt in hot water; instead, they can dissolve or break down more quickly due to the heat. The gelatin and gum arabic in Mentos may soften, but the primary reaction of Mentos with carbonated beverages is due to the physical structure of the candy, which facilitates rapid nucleation of carbon dioxide bubbles. In hot water, the candy may lose its shape and integrity faster than in cold water, but it won't "melt" in the traditional sense.
