The salt dissolved fastest in the warm water.

The salt dissolved fastest in the ice water.

The salt dissolved in the same amount of time at all three temperatures.

The salt dissolved fastest in the room-temperature water.

I chose the first one but can someone double check for me? Thx

Esteban Andrade · Answer 1

The salt dissolved fastest in the warm water.

Step-by-step explanation:

You were correct.

The salt dissolved faster in the warm water, because the water molecules have more kinetic energy to dislodge the salt particles from the surface of the crystal.

The colder the water, the less kinetic energy the water molecules will have, and the more slowly the salt will dissolve.

doesnt salt desolve ice? so wouldn't the salt dissolve in the ice water?
