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.

The chemical bonds of the solid are broken faster.

Explanation:

As the temperature of a solution is increased, the average kinetic energy of the molecules that make up the solution also increases. The increased vibration (kinetic energy) of the solute molecules causes them to be less able to hold together, and thus they dissolve more readily.

chemical properties are the characteristic of matter which can only be observed by changing the chemical identity of a sample like flammability reactivity and toxicity.
