Figure shows the isotherms of fixed mass of an ideal gas at three temperatures T_(A).T_(B) and T_(C ) then:-

Three bodies A , B and C have equal surface area and thermal emissivities in the ratio e_(A) : e_(B) : e_(C) = 1 : (1)/(2): (1)/(4) . All the three bodies are radiating at same rate. Their wavelengths corresponding to maximum intensity are alpha_(A), alpha_(B) and alpha_(C) respectively and their temperatures are T_(A) , T_(B) and T_(C) on kelvin scale , then select the incorrect statement

One mole of a gas is in state A[P, V, T_(A)] . A small adiabatic process causes the state of the gas to change to B [P + dP, V + dV, T_(B)] . The changes dV & dP are infinitesimally small and dV is negative. An alternative process takes the gas from state A to B via A rarr C rarr B . A rarr C is isochoric and C rarr B is isobaric path. State at C is [P + dP, V, T_(C)] . (a) Rank the temperatures T_(A), T_(B) and T_(C) from highest to lowest. (b) Find g of the gas in terms of T_(A) , T_(B) and T_(C) .
