Temperature is one of the factors that influences the reaction rate between substances. It measures the average speed of particles, so if the temperature is high (in hot water), the particles will move faster and collide with other particles more forcefully.
So when you add the jello, the particles are going to dissolve faster because of the increased movement of water molecules. They collide more forcefully and more often than in cold water, increasing the rate of reaction as well as increasing the amount of jello dissolved in the water.

Do solids dissolve better in hot or cold water?
Dissolving is caused by the small rapid movements of the atoms or molecules. The faster they are moving, the better substances dissolve. As the molecules have more energy and therefore move faster in hot water, substances dissolve better there.
How fast does coffee dissolve in hot water in cold water?
Instant coffee granules dissolve faster in hot water than in cold water.
What will make bar soaps dissolve faster in water?
using hot water will dissolve it.
Will hot or cold water make sugar dissolve faster?
it only takes about 3 minutes to dissolve sugar in hot to boiling water. When it could take about a hour for cold water.
Does caffeine dissolve in acetone?
Caffeine is soluble in water - but not HIGHLY soluble. You can dissolve a lot more caffeine in the same volume of water compared to what will dissolve in an equal volume of acetone. It dissolves better in hot acetone than in cold acetone.
Do sugar cubes dissolve better in a hot place?
They will dissolve much quicker in warm or hot water than in cold water.
Who is better to dissolve in hot water or cold water?
hot water because the molecules are moving faster
Can you eat jello raw?
If you mean the Jello mix powder right of the box - yes, you can. It isn't really 'raw'. The hot water is needed to dissolve the gelatin - not to cook it. Jello out of the box was a special treat when I was growing up.
Does sugar dissolve better in hot water than in cold water?
yes.
Does powdered juice dissolve better faster in hot or in cold water?
Powdered juice dissolves faster in hot water, but tastes better in cold water.
Does Alka-Seltzer dissolve better in hot water or cold water?
All solutes (e.g. Alka-Seltzer) dissolve better in a warmer solvent (e.g. water).
Does baking soda dissolve better in hot warm or cold water?
To dissolve baking soda in hot water one would need to pour hot water on the baking soda and stir it with a spoon. Baking soda that is dissolved has lessens the leavening action of the soda.
Do solids dissolve better in hot or cold water?
Dissolving is caused by the small rapid movements of the atoms or molecules. The faster they are moving, the better substances dissolve. As the molecules have more energy and therefore move faster in hot water, substances dissolve better there.
Is jello better hot or cold?
hot, if cold, there is a posibility of a cold!
Does jelly dissolve better in hot water or cold water?
Jelly dissolves faster in hot water because water molucules move faster at a higher temperature.
Why does jell o dissolve better in hot water?
Jelly dissolves faster in hot water because water molucules move faster at a higher temperature.
Can cold water clean dishes?
It can, but hot water works better because it helps to dissolve grease and hardened food better than cold.
