\(PV\,\, = \,\,\,\mu RT\,\, \Rightarrow \,\,\,\,T\,\, = \,\,\,\frac{{PV}}{{\mu R}}\,\,......\,\,\,\,(i)\)

પરંતુ \(\mu \,\, = \,\,\,\frac{M}{{{M_w}}}\) અને \(\rho \,\, = \,\,\,\frac{M}{V} \) \(M\,\, = \,\,\rho V\,\,\,\,\,\therefore \,\,\,\mu \, = \,\,\frac{{\rho V}}{{{M_w}}}\)

સમીકરણ \((i)\) પરથી \(T\,\, = \,\,\,\frac{{PV{M_w}}}{{\rho VR}}\,\, = \,\,\frac{{P{M_w}}}{{\rho R}}\)

આપેલ :\( P = 1.4 \times  10^9 \,atmosphere = 1.4 \times  10^9 \times  1.01 \times  10^5 Nm^{-2}\)

\(\rho  = 1.4 \,g\, cm^{-3} = 1.4 \times  1000 kg m^{-3},\, Mw = 2 \times  10^{-3} kg/mol\)
