PM stands for particulate (微粒的)matter: the term for a mixture of solid particles (粒子)and liquid droplets in the air. Some particles are large or dark enough to be seen by our eyes. Others are so small that they can only(1) ___ (discover) with a microscope. These particles...
When creating sentences, you should be careful which one you’ll use unless it doesn’t matter in that particular sentence. With practice, you’ll get the hang of them! As mentioned above, in many cases, you can use the particles ~이/가 (~i / ga) and ~은/는 (~eun / neun...
What is the atomic mass of an atom that has 6 protons, 6 neutrons, and 6 electrons? What is particulate matter composed of? What substance is made up of one type of atom only? What are atoms made of? What is the mass number of an atom? What is the atomic mass/weight of an atom...

phase, form - (physical chemistry) a distinct state of matter in a system; matter that is identical in chemical composition and physical state and separated from other material by the phase boundary; "the reaction occurs in the liquid phase of the system" colloid - a mixture with properties ...
The leading theory says dark matter consists of weakly interacting massive particles, or WIMPs (S&T: January 2013, page 26). Popular model takes big hit Theorists have proposed various new particles that could make up dark matter, including weakly interacting massive particles (WIMPs) predicted by...
11. Recent research interests in active matter are mainly motivated by its emerging phenomena that do not exist in equilibrium systems, its biological relevance12,13,14, and its potential applications in autonomous materials systems15,16,17,18,19. Our current understanding of active matter is ...
