A student observes that in the photoelectric effect, photons need to have well-defined energies in order to move electrons. Which statement is correct about this explanation? (1 point) a. A wave model of electromagnetic radiation can sufficiently explain the photoelectric effect.

b. Either a particle model or a wave model of electromagnetic radiation can sufficiently explain the photoelectric effect.

c. Neither a particle model nor a wave model of electromagnetic radiation can sufficiently explain the photoelectric effect.

d. A particle model of electromagnetic radiation can sufficiently explain the photoelectric effect.

freezing

deposition

condensation

explanation;

melting also called fusion is the process where solid becomes liquid, sublimation is the process where solid becomes gaseous without first changing to liquid, deposition involves change from gaseous to solid state, freezing involves change from liquid to solid, boiling or evaporation involves change of liquid to gaseous state, while condensation is the change from gaseous state to liquid state.

endothermic reactions involves absorption of heat from the surroundings or the environment while exothermic reactions involves loss of heat energy to the surroundings.

in this case, sublimation, evaporation and melting are endothermic reactions (gain energy from the environment) while, freezing, deposition and condensation are exothermic (loss of energy to the surroundings) reactions.
