It is called convection. When warm air, or current, moves up and disperse outwards as cold air, or current, moves into the warmer region.
Answer: 7 neutrons
Explanation: Atomic number refers to the number of protons in the nucleus of the atom. Also you can treat atomic mass as how many particles (protons and neutrons) are in the nucleus of the atom. So for this problem:
14 particles - 7 protons = 7 neutrons (and we know all that's left over is neutrons because we subtracted all the protons)
An atom consists of three sub atomic particles which are protons, neutrons, and electrons. ... This nucleus is surrounded by the electrons as electrons revolve around the nucleus. Thus, we can conclude that out of the given options, a core of protons and neutrons surrounded by electrons best describes an atom.
and y'all still In school?
Answer:
When the kinetic energy of particles in liquid increases, the particles are pushed farther apart. This can result in the expansion of matter. More pressure will be exerted on the container in which this liquid is stored.
