systems a, b, and c are classical gases (not necessarily ideal), each with the same number of molecules n (or same number of moles n if you prefer), where n is constant. we can measure pressures and volumes pa, va; pb, vb; and pc, vc for each system. when a and b are in thermal equilibrium, our measurements show that their pressures and volumes satisfy: when a and c are in thermal equilibrium, we find where α, β, and γ are constants. ta of system a in terms of pa, va and constants ts of system b in terms of pb, vb and constants tc of system c in terms of pc, vc and constants a) express the temperatures: b) find the equation relating pb, vb and pc, vc that is satisfied when systems b and care in thermal equilibrium. c) which of these systems is an ideal gas?

An  atom  (ours, not carroll's) consists of a positively charged  nucleus, surrounded by one or more negatively charged particles called  electrons. the positive charges equal the negative charges, so the atom has no overall charge; it is electrically neutral. most of an atom's mass is in its nucleus; the mass of an electron is only 1/1836 the mass of the lightest nucleus, that of hydrogen. although the nucleus is heavy, it is quite small compared with the overall size of an atom. the radius of a typical atom is around 0.1 to 0.25 nanometres (nm), whereas the radius of a nucleus is about 10-6  nm.  *  if an atom were enlarged to the size of the earth, its nucleus would be only 200 feet in diameter and could easily rest inside a small football stadium.read more on -
