In an adiabatic process, the body neither absorbs heat nor does it refuse energy, i.e. in this phenomena there is no heat exchange (Δ Q = 0).
Thus from first law of thermodynamics, W = -Δ U
A radiation of 500nm is incident on a metal surface whose work function is 3ev.why do we not observe the phenomenon of photoelectric effect? Ans) Because the energy of radiation i
