Lightbulb Sugar

Salt and sugar would be my first guess. They dissolve faster when the water is hot

Default I would say

I would say it would be cool to find out for yourself. So here's and idea.
Take at least five different substances. Then put each in a glass of cold and hot water. Time them to see. To make things interesting, stir up the water after placing each substance in the glass and see if that has an effect.
If you need help, turn to God... no matter what, he will be there always

The Harder the Conflict... The Sweeter the Victory
Believe, and things will happen

Well im not too sure but I think is the ice Oh and in order to find out you should make a list of things that dissolve in the water then try each one of them and keep track of the speed of each object and the fastest will win!well good luck!=)

sciencefreak is a brilliant scientist admired by others

That is a some-what vague topic....

When water is heated, it's molecules gain energy and move about rapidly. Thus, they create more inter-molecular space and thus, a solid will dissolve quicker...

Some substances like kerosene and oil do not dissolve in water but float on it as their density is lower than that of water..

Some substances like coal sink without dissolving as their density is higher than that of water...

Also, the molecules of these substances do not mingle with those of water.

The Newtons and friends were taking tea
Beneath the boughs of an apple tree,
When a falling fruit landed on the
Head of the head of the family.
Mrs. Newton cried, 'Well deary me!
That could've caused an injury'.
But clever Isaac alone could see,
The situation's true gravity.
