Why is it easier to dissolve sugar or salt in hot water than in cold water?
In: 2
You need to supply energy to the bonds in the compound, atoms to break them down and hot water has more energy than cold water
If I remember correctly, it’s about collisions. Molecules need to collide with one another to have a reaction. Since molecule move around more (and faster) at higher temperatures, more collisions happen.
Or, even more simply: those molecules are like cars in a demolition derby. If the cars are cold and moving slowly, they just kinda bump each other. If the cars are zipping around, though, they’ll smash and fall apart.
