A stereo speaker is made of a flexible cone-shaped material that vibrates, creating a sound wave. A sound wave formed be a speaker travels through air to your ear as a series of compressions and rarefactions of air molecules. Which statement classifies the sound wave?

transverse wave in which the particles of the wave move in a direction parallel to the wave motion

longitudinal wave in which the particles of the wave move in a direction parallel to the wave motion

transverse wave in which the particles of the wave move in a direction perpendicular to the wave motion

O longitudinal wave in which the particles of the wave move in a direction perpendicular to the wave motion

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.
