In terms of the measurable properties (i. e. p, v,t, cp, and cy) and express (a) н their derivatives. note that you also need the fundamental enthalpy equation, dh tds vdp. comment on the real world situation where the derived expression typically applies (b) ат show that for an ideal gas, (c) is zero and comment on the physical significance h of it.

Consider hydrogen in an excited state n = 5n=5 that emits photons to reach the ground state. there are various possible transitions other than straight to the ground state that can occur; for example, it can drop to the n = 3n=3 state followed by the n = 3n=3 to the ground state transition. which of the possible transitions will result in the emission of a photon in the visible region?
