Which of the following statements best explains dissolution?
a. random molecular motion leads to collisions between the solute and solvent which causes the breaking of intermolecular forces.
b. the attraction of the solute to itself is greater than the attraction to the solvent. c. random molecular motion does not interfere with the intermolecular forces between the solute and solvent particles.

The diagrams show objects’ gravitational pull toward each other. which statement describes the relationship between diagram x and y? gravity attracts only larger objects toward one another. gravity attracts larger objects only if they are close to one another. if the masses of the objects increase, then the force between them also increases. if distance between the objects increases, then the amount of force also increases.

Which theory was contradicted by experiments with the photoelectric effect? light spreads out after it passes through a small opening. as soon as light strikes metal, electrons will be ejected. visible light, regardless of color, will cause the ejection of electrons when striking metal. the kinetic energy of ejected electrons depends on the frequency of light that strikes the metal.
