Describe the three steps of solution formation. be sure to include the details regarding the dissolving of the substance
Elza [17]

The three steps involve;

Step 1: Separation/expansion of the solute particles

Step 2: Separation/expansion of the solvent particles

Step 3; Combining the solute and solvent particles


The first two steps are usually endothermic. Step 3, nonetheless, can be either exothermic or endothermic and is significant in determining whether the dissolving process will be endothermic or exothermic.

This question is for science. which options describes the particles of water as liquid water actively boils to become steam?
-BARSIC- [3]

Answer:

The correct option is;

a. The particles will gain a large amount of kinetic energy

Explanation:

As the water temperature reaches 100°C, which is the boiling point for water at atmospheric pressure, the continued heating is then used to break up the strong inter molecular forces between molecules of the water  such that the individual molecules are free to move about and due to the high temperature, have gained considerable amount of kinetic energy for the to rise to appreciable height and to also spread.

The heat which converts water into steam is called latent heat as during the boiling phase, the temperature of the water remains constant.
