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 :

Options:

Answer:

Solution:

On giving same amount of heat at constant pressure, there is no change in temperature for mono, dia and polyatomic. $(Δ Q)_{P} = μ C_{p} Δ T (μ = \frac{No. of molecules}{Avogedro’s no.})$ or $Δ T \propto \frac{1}{no. of molecules}$
