Question

TRUE or FALSE 1. Stirring a solution will make the solute dissolve slower. 2. As the temperature of a liquid increases, the rate at which a solid solu dissolves decreases. 3. As the size of solute particles increases, the rate at which the solute dissolves increases. 4. Solutions form when a solute dissolves in a solvent. 5. Heat causes molecules on sugar to leave sugar cube more rapidly w places in a solution. 6. The rate at which a solid solute dissolves can be changed. 7. The larger the size of solute particles, the faster the solute dissolves 8. A sugar cube dissolves faster in a glass of cold water than in a glass water. 9. If you put a sugar cube in a glass of water and do not stir it, some sugar will dissolve. 10. A cool solvent dissolves less solute than an equal amount of warm solvent.​

Answer 1

Answer:

Dissolving sugar in water will occur more quickly if the water is stirred. The stirring allows fresh solvent molecules to continually be in contact with the solute. ... It is important to realize that neither stirring nor breaking up a solute affect the overall amount of solute that dissolves.

Explanation:

For many solids dissolved in liquid water, the solubility increases with temperature. The increase in kinetic energy that comes with higher temperatures allows the solvent molecules to more effectively break apart the solute molecules that are held together by intermolecular attractions.

Answer 2

Answer:

1. FALSE
2. FALSE
3. FALSE
