Question

Figure shows the variation in temperature $(Δ T)$ with the amount of heat supplied $(Q)$ in an isobaric process corresponding to a monoatomic $(M)$ , diatomic $(D)$ and a polyatomic $(P)$ gas. The initial state of all the gases are the same and the scales for the two axes coincide. Ignoring vibrational degrees of freedom, the lines $a, b$ and $c$ respectively correspond to :

On giving same amount of heat at constant pressure, there is no change in temperature for mono, dia and polyatomic. ( Δ Q ) P ​ = μ C p ​ Δ T ( μ = Avogedro’s no. No. of molecules ​ ) or Δ T ∝ no. of molecules 1 ​
