  1. A student dissolved equal amounts of salt in equal amounts of warm water, room-temperature water, and ice water. Which of the following is true?

The salt dissolved most quickly in the warm water.

The salt dissolved most quickly in the room-temperature water.

The salt dissolved most quickly in the ice water.

None of the above

1.one substance must dissolve another : the solvent breaks the the solute causing it to dissociate into the solvent it can be both solids or gases that dissolve in the solute

2.the melting point will be higher than 100 degrees as the salt causes the solution to gain a higher melting point

3.either released or absorbed : energy is required to dissolve the solute but the solute may also release energy

4.the salt dissolved most quickly in the warm water : as there is more energy for the solute to dissolve 

hope that helps
