Accepted Answer
Conduction is the system by which warmness strength is transmitted thru collisions between neighboring atoms or molecules.Molecules must collide if you want to react. if you want to successfully provoke a response, collisions must be sufficiently energetic (kinetic energy) to interrupt chemical bonds; this energy is called activation electricity.Convection : molecular collision. It should be Conduction. Convection is the right solution. As they said molecular collision within the query in order that it's mean the motion of particle so that real migration of debris are best seen in convection.Some commonplace synonyms of collision are concussion, effect, and shock. while these kinds of phrases mean "a forceful, even violent touch between two or more things," collision implies the coming collectively of two or greater things with such force that each or all are damaged or their progress is seriously impeded.Learn more about molecules here:https://brainly.com/question/26044300#SPJ4
