Not sure how in depth or what level of particles but I will go as deep as I know. The matter that makes up the world is comprised of 12 particles which are known as fermions. There are 12 fermions which are made up of 6 quarks (up, charm, top, Down, Strange, Bottom) 3 electrons (electron, muon, tau) and three neutrinos (e, muon, tau). Technically, only the up quark, down quark, electron, and electron neutrino are necessary to create all known matter since others would simply be very unstable and decay into those particles. The other type of particles are known as Bosons. These particles transmit forces and all sorts of different interactions. I have included a photo from online which describes the main characteristics of each elementary particle.
boiling, salt water will separate the salt from the water through the physical change of water from a liquid to a gas, leaving you with just salt left over.
Answer:
well according to salesman they take out all and out all bacteria that is in the water that the water filters installed in the systems already don't take out so in other wordsthere and the water filter takes that out
