Q) A space eapsrtlo built with Aluminum alloy descends to earth surface from outer space {3 K. 13.22 Pa}. After reaching into the stratosphere. the reentry capsule interacts with air molecules and generates lot of heat. often the surface temperatures go beyond 1500"\"(3 at atmospheric pressure before landing into Ocean. (:1) Consider enthalpy and entropy as a function of (T. P) and develop the expressions for ti]! and (is that consists of CF. [3, V, T. dT and (11'.
