If the solvent's polarity and the solute's polarity are comparable, the solvent will dissolve the solute.

Most solids become more soluble in water as the solution's temperature rises. But as temperature rises, gases become less soluble.

The solubility of gases is exactly proportional to the pressure of the gas above the liquid (but not of liquids or solids).

Intensive property, does not depend on the amount of substance being examinded

Extensive property, depends on the amount of the substance.

Process wherein the physical properties of a substance changes without changes from the chemical composition.

Chemical change is a process where one or more substancesare converted into one or more new substances, may be called chemical reaction.

Permanent or sudden change in color, temperature, or odor, bubbling, evolution of gas, formation of precipitate

It is the energy of the moving object.

If the speed of the object increases, the kinetic energy increases as well. Hence, when the speed of the object decreases, the kinetic energy decreases.

When particles are heated, they move faster. thus, when they are cooled, they move slower.

Substance that cannot be broken down into simpler substances even by a chemical reaction.

Substance composed of two or more elements combined in definite proportions.

Mixture in which the composition is uniform throughout the mixture.

Mixture in which the composition is not uniform throughout the mixture.
