D)proton, electron, neutron, and neutrino

Question

Quizplus · Accepted Answer

Threshold temperature is the minimum temperature required for a particle to initiate a particular reaction or process. Neutrinos have the highest threshold temperature among the given particles because they interact very weakly with matter, which makes it difficult to detect them. The electron has a lower threshold temperature than the proton and neutron because it is lighter and experiences less resistance to start a process. Finally, the proton has a lower threshold temperature than the neutron because it is positively charged, while the neutron is uncharged and needs an external trigger to start a process. Therefore, the correct order of increasing threshold temperature is neutrino, electron, proton, and neutron, which is given in choice C.
