Question

Why does increasing the temperature make a solid dissolve faster?

- The solvent molecules bump into the solid more often.
- The solid is melted before mixing into the liquid.
- The chemical bonds of the solid are broken faster.
- The pressure of the solute on the solid is increased.

Answer 1

Answer:

The solvent molecules bump into the solid more often

Explanation:

Answer 2

Increasing the temperature makes a solid dissolve faster because the solvent molecules bump into the solid more often.

What happens when you increase the temperature of the solvent?

If we heat the solvent, the average kinetic energies of its molecules increase. Hence, the solvent is able to dislodge more particles from the surface of the solute. Thus, increasing the temperature increases the solubilities of substances. For example, sugar and salt are more soluble in water at higher temperatures.

Does raising the temperature make a substance dissolve faster in a solvent?

The temperature of the solvent is another factor that affects how fast a solute dissolves. Generally, a solute dissolves faster in a warmer solvent than it does in a cooler solvent because particles have more energy of movement.
