An increase in temperature causes a decrease in the amount of gas able to dissolve in a liquid solvent. Why does this occur? OA.
increased solubility
ОВ.
increased kinetic energy
ОC. .
large molecules
OD. decreased potential energy

Why do scientists believe that light is made of streams of particles? scientists believe that light is made of streams of particles because only the presence of photons can explain phenomena observed during experiments on the photoelectric effect. these observations include only some frequencies of light causing the ejection of electrons, no time gap existing between light striking a metal and electrons being ejected, and intensity having no effect on the kinetic energy of the ejected electrons.
