\(T_1 = 27 + 273 = 300 K,     T_2 = 627 + 273 = 900 K\)

સમોષ્મી ફેરફાર માટે, \(P^{1 -\gamma} T^{\gamma} =\) અચળ

\(\therefore \,\,\,{P_1}^{1 - \gamma }{T_1}^\gamma  = {P_2}^{1 - \gamma }{T_2}^\gamma \,\,\,\,\,\therefore \,\,{\left( {\frac{{{P_2}}}{{{P_1}}}} \right)^{1 - \gamma }} = {\left( {\frac{{{T_1}}}{{{T_2}}}} \right)^\gamma }\)

\(\therefore \,\,\,{\left( {\frac{{{P_2}}}{{{P_1}}}} \right)^{\gamma  - 1}} = {\left( {\frac{{{T_2}}}{{{T_1}}}} \right)^\gamma }\,\,\,\,\,\,\,\therefore \,\,{\left( {\frac{{{P_2}}}{{{P_1}}}} \right)^{\frac{1}{2}}} = {\left( {\frac{{{T_2}}}{{{T_1}}}} \right)^{\frac{3}{2}}}\)

\(\therefore \,\,{\left( {\frac{{{P_2}}}{{{{10}^5}}}} \right)^{\frac{1}{2}}} = {\left( {\frac{{900}}{{300}}} \right)^{\frac{3}{2}}} = {(3)^{\frac{3}{2}}}\,\,\,\,\,\,\therefore \,\,\,\frac{{{P_2}}}{{{{10}^5}}} = {3^3}\)

\(\therefore \,\,\,{P_2} = 27 \times {10^5}N/{m^2}\)
